Hello everyone ,
This is my first post and I don't know if the stuff I'll mention have already been mentioned on other posts so bare with me.
I will keep on updating the post with other people's additions.
Cell cooldown timers.
There is a visual indicator on when you can request cells however I can't see any for your donation cooldown per rarity. Seems like I'm always on cooldown. It will be nice to tell me for example " you will be available to donate rare cells in 4 hours" . I found out you have to click on the exclamation mark to see the cooldown remaining. However I would love a small floating text with the remaining reset time, whenever I click the greyd donate button.
Facebook account.
Big fan of ditching Facebook servers and generally Facebook integration. However I still don't like the fact that our progress is saved in Facebook account, please try working it out with google account! What if I want to delete my FB account? Adding custom profile photos would be nice!
PvP matchmaking.
Seems like the people that I find are always ~150 points stronger if not more , I would love to see the gap between my points and enemy's get shorter.
Adventure map navigation.
This is also totally hell to find specific levels. Endless swiping the screen. Some kind of sorting would be nice. For instance sort according your stars / scores / level theme / level number.
Eggs/Hatching.
It would be cool if you could send the egg directly to storage instead of hatching it. Or a hatching guardian maybe.
Minor PvP revenge attack bug?
I encountered a weird bug. When I logged and the PvP report screen popped I casually revenge attacked the first person on the list. After defeating him, the screen with the revenge was still there and I could attack the same person twice.
Ad rewards.
Sometimes even if the ad is finished the reward is not given and you have to either rewatch or you waste your ad cooldown.
Relic animations.
A bit faster relic animations would be better imo.
PvP monster restrictions
PvP is dull, at higher ranks you always see the same monsters. How about adding book restrictions each season, as are in team wars?
Event items & Monsterwood
Monsterwood is sometimes buggy, either by not giving the reward or sometimes by not having any videos to watch. Adding event items such as Afro wig in imigbo event feels not fair for some who experience technical difficulties.
Breeding event transparency
I know it may not be a good financial move to add the percentage rates of the breeding events (since if the percentage is low many players won't be arsed to participate, following in less gem spending) but will make players happier, it will make me happier for once
