2 main things i noticed. 1 the big drake is way too powerful, especially compared to the loot it gives. 2 In the update section it says that you get the third hero at level 40 fort but that isn't true you get it at lvl 60
Noted, hero at 40 will be fixed next update. Also 0.91 added more ranks(max of 5) for the lower mobs so you can grind on them for greater rewards without having to make the huge jump to the next enemy until your heroes are ready.
