finished the game on Hard. As usual, i found it wasn't TOO hard except the beginning and some boss fights, and until i recruited a druid. druids are op in this game.
my strategy was equipping everyone with slow, high DMG ranged weapons (arbalests and arquebas whatever), sneak and tell everyone to blast one fool one the egde of the fog of war. once the rest of his friends charge me, i switch everyone to melee weapons in the 2nd slot and start buffing/aoe-ing.
also, positioning all my guys behind a door made some fights much easier. i had Eder and a monk (i rolled) stand in the oor way, the priest buffed everyone, Aloth and the druid nuked from behind and occasionaly my rouge main would backstab when possible.
great game overall, but i wont get the expansion, i overdosed and need a breather. gonna play Wasteland 2 next
