There are allot of new things being added to monster legends and new content is always coming out but I feel like resource dungeons have been forgotten a bit. There are limited time dungeons such as new monster key survival dungeons, nemesis dungeons, maze coin dungeons, etc. but then there’s also the permanent dungeons such as the rune chest dungeon, the easy and hard gem dungeons, the epic cell dungeons, elementium dungeons, and food and gold dungeon but I still think it can be improved even further. 
 The food and gold dungeon especially. I think the higher level you are the more food and gold you should get from the dungeon because the late game and mid game players can’t really do much with a few thousand food and gold and after completing the adventure map resources don’t flow in as fast. Farms don’t give as much food for their price needed to level up monsters later on and if the dungeons resources went up the higher level you are I think it would give much more of a purpose for completing the dungeon. Maybe making the current food/gold dungeon into an easy food and gold dungeon while adding a hard food and gold dungeon which is more difficult but gives much more resources than the current one.
 I think the rune dungeon is a good fun way of expanding your rune collection which made me think of relics. By adding a relic dungeon it will allow players to gather more relics for leveling up others or if their early game and maybe even some mid game players they can get the chance to get new relics to play around with. It could rotate with the rune dungeon and there could be an easy and hard relic dungeon. The layout that the gem dungeons and elementium dungeon have. The easy relic dungeons could give mediocre amounts of relic loot such as maybe up to 5-10 bronze chests and 1 silver chest for the final node and the hard difficulty one could have 7-12 bronze chests, 2-5 silver chests, and 1 gold relic chest on the final node. I think this will give players a fun way to collect relics. The other idea I had for this was that I thought of if there should be requirements for the relic dungeons like maybe a new type of requirement such as you can only use a monster with a staff slot, a monster with a trap slot, and a monster with a armor slot. This will make getting relics a bit more challenging and interesting.
 Cell dungeons are a cool idea and so is the monthly log in with the monthly showcased monster but you only get 80 cells instead of the full 100 to craft. I think it would be a cool idea to add a dungeon that lasts that month and if you complete it you end up getting the last 20 cells of the monster. You could get the cells like the epic cell dungeon although the dungeon would either be shorter due to there only being one monsters cells in the dungeon rather than the normal two or the cells can be spread out more with the same amount of nodes. This will allow you to spend those 20 other elementium or elemental cells on ranking up or on something else.
 I believe that these additional dungeons will make resource dungeons much more interesting and fun and will give players a wide selection of dungeons to pass the time with. I myself have allot of fun with dungeons after doing my multiplayer attacks and I usually can finish most of the available dungeons in the matter of a day or less but then I’m left waiting till the dungeons refresh and so if the dungeons are harder and/or more rewarding then I think there will be more of a variety to play because at the moment some of the dungeons aren’t very beneficial to me and I play them just to play them such as the epic cell dungeon (which I don’t need because I use legendaries) and the food and gold dungeon (which give little to no benefit to a player such as myself).

I do like the idea of the permanent dungeons but I would tweak it. To start off I agree with the easy and hard dungeon variety, but not a lot of people actually use the food and gold dungeons so I don’t think changing that dungeon would be affective enough to make a lot of people use it. I do like the idea for the monthly monster having a dungeon to get the rest of the cells. But what I’m mainly concerned about is the relic dungeon you talked about. I feel that it could be overkill for a gold relic chest at the final mode because 75% I get a diamond relic out of a gold chest and I feel for a dungeon that is not fare. Although that is just my luck I still feel this way about the relic dungeon. I see that you want it in a hard dungeon but there will have to be serious requirements for the dungeon. I think adding a variety of dungeons will better help the game and help the players. I mostly agree with your thoughts.

@brogan-madden I do agree that the amount of relics may be an overshoot but the dungeon will have requirements and I wouldn’t mind if there are harder monsters to face to make the long and difficult fight worth it. Most dungeons are easy and you can sweep through them fairly quickly and the harder ones are only hard due to just high damage. I think they should add monsters that attack in a more strategic way such as using more status effects in battle. Also the only reason people don’t do the food and gold dungeon is because at the moment it’s useless but with my changes I think they will then be more liked.

This exact point is why I made an forum account today and wanting to voice this somewhere. I am a new player, and found it odd that I can't do any dungeons today, at all, because I am lvl 20 now, and I went into the only daily dungeon available to me just to find the 1st set of monsters are lvl 60. Like WTH? This in no way encourages new players if literally their only choice is to play something they have no chance of competing against. I agree with Permanent dungeons so players at different levels can actually have the option of enjoying a dungeon daily. OR dungeons and "event" dungeons could scale with players levels. Otherwise what's the point? It's not even a goal, when by the time I hit lvl 60+ the event isn't even available anymore. So why not scale to players? Right now I finally can spend my xmas keys on something JUST to find I cannot. I'm lvl 20 the xmas key monsters are lvl 60! So I have to sit on these keys in my inventory until next years xmas. Really? Why would I pay real money on a game like this?

My options today is collect my gold play my measly 4 matches in pvp, try 4 times to beat an adventure map boss that I am in no way able to beat yet and sign off. No daily resource dungeon no map maze (because without the support of resources to level and no maze coins earned the game comes to a crawl or halt). Just come back tomorrow and see if I have any dungeons to play with. It feels like this games only concern is for end game players. Which is funny actually. Most games focus on new players and forget about end game content. But in 2 years when I am lvl 60 I can come here with a new perspective maybe.
