I've played little, only 3 games, but I've read a lot and seen a lot of videos and I see a too obvious unbalance.
- Waiqar are very slow. Their initaitives are quite sh*tty. Even Ardus is slow to be a character.
- Ardus hits hard, buy kari is ridiculously powerful, she has killed 6 archers with her skill and the theorical limit is 8!! Ardus' CC skill is quite ok, but he shouldn' be more expensive than kari.
- Move slow: reanimates can only charge 2!!!!!
- Easy to kill: reanimates have no armour choice and have low initiative to use +1 defense. Carrions are tougher and though die much easier than golems.
- Blights are powerful but it's almost imposible to blight in close combat, so after turn 2 or 3 it's almost worthless.
- The upgrade cards they really need are mostly on those expensive upgrade boxes. I beg them to release card packs with decent variety of the best cards, specially for waiqar
In conclusion, they needn't enormous overhaul, but they need a few key improvements to be able to bear with their lack of movility, their unbereable initiative and their weaker stats/control pannel in general, and blighting in combat is probably the key.
I want to debate about "how to rebalance the waiqar" and to predict how future expansion cards work on it.
