With the Introduction of the Vault, we pretty much got into the problem of needing to actually pay gems to be able to keep more monsters, this is due to the fact that well, you need to pay gems to unlock vault slots, and with the constant increase of price, is not very appealing.
The vault was introduced because we had the need of keeping more monsters and adding more islands and habitats is not feasible due to device limitations, it will make the devices to take a lot of time to load, etc, at least thats the reason stated by SP.
Now, after having a conversation with a couple of team mates (bluedeath & nightmare Ninja), they asked why a feature like Dragon City Ancient world can't be introduced, I have never played, so I wen't to check it out, and for those who don't know, Dragon city has a portal that will transport you to another world.
Checking this gave me an idea that I obviously want to share here.
The universe of monster legends is build on the premise that there are different Elements, monsters are categorized by those elements, and they all live on a group of islands.
At some point those the islands are just not enough to hold them all, and with the constant release of monsters, we reach the cap fairly fast.
What I'm proposing is a revamp of the ML Universe Islands, a feature like Dragon citys ancient worl can be introduced, maybe even we can unlock Words, Imagine having the same limitations as the main Island, 90 habitats, and 12 islands but per world.
A new World event for each World for each element can happen, and players can unlock a new world, then on that world they can unlock the islands, like in the original first world, you just move between worlds, like you move between players when you visit another player Monster legends world, so that mechanism is already build on the game.
Each world will have islands, habitats, gold generation, etc, and since we will be able to distribute monsters on those worlds, the loading time of the game will be just the same on each world when you move between them, even, the cap can be reduced and distributed on those worlds, but obviously allowing players to have more monsters in total.
Water world, it can only keep water monsters, and so on.
The main world can be used to hold your main monsters, the ones that you use on pvp, adventure map, team wars, etc, and you will have the hability to move monsters between those worlds.
I think a revamp like this will be benefitial to the game, it will allow us to collect more monsters, it will give high level players something to do besides pvp and team wars, it will prolong the life of the game by releasing a new world like every year with a huge event, it opens posibilities like having like exclusive or dedicated guardians on each habitat.
