Ok, some issues after few days:
1. Three different type of feats in three different places isn't very convenient. Please optimize feat layout and tracking if possible.
2. Conquest store doesn't look good so far - too many useless stuff and not too many useful.
3. The existence of challenge gear in the final box is... disturbing. Fighting for two weeks and get MK4 Carbanti as reward is NOT good. There may be small chance to get bad rewards but it will make things only worse for those who will get it.
