Possible ways to make the game even better [edited by Mod for clarity]
1) remove 3* pulls from alliance feed
2) implement a rematch button for duels
3) get rid of the god-awful duel event or make the rewards better
4) update the uselessness of quest crystals
5) increase overflow or remove it altogether
6) for the love of Chthulhu, let us sell from overflow
7) increase the gain rate from t3cc and t2cc dailies
8) increase the loyalty from help... 1K is nothing
9) update alliance crystals, max sig crystals and AW crystals
10) update rewards for solo and alliance events
