I disagree with this as well. I enjoy this system that makes it so we can't just stun everyone on turn one like in the first game. You have to set your magic damage dealers to focus the ones without magic armor, and the opposite. Positioning at the start of the combat + using slows, kiting the melee enemies etc. Way more interesting than just casting rain + electricity on all enemies every single combat.
How it is fun cheesing here and there and using only crossbows/summons and oil?
