is this an error, or intended? is it to balance the class?

Is someone still playing this game? :) I need to invite someone to trigger the achievement.

Someone looking for help for the achievement?

Thinking dwarf, archer, and knight. Just curious of potion types mostly. Was thinking all health potions depending how hard the sorcerer hits with his lighting. But there are potions that give shields against magic. Also curious about equipment types. Pretty sure armor didn’t matter much in my fight during normal mode - everyone got hit equally. Just wanted some opinions. All my heroes have maxed abilities and I know their spell rotations fairly well....

I just finished with Dwarf, Monk, Knight, anyone use a different set of 3 for most of the game?
