Larian Studios Forums Divinity - Original Sin Divinity Original Sin - Beta my feedback on hard difficulty

I think more interesting hard difficulty shouldn't just have an increased enemies level, HP, damage output etc., but also have these things:
-enemies use higher level skills (for example, not flare but fireball) and use them more often
-there should be more enemies in every encounter (but to maintain balance, experience gain for every encounter should not be higher than on easier difficulties)
-there should be more hazardous objects, like oil barrels, in enemy encounter areas
-negative effects, like being stunned, should last longer
-allow companions permadeath if they take damage well above their HP number, like, say, 200% of their HP number (also a good thing in general because it encourages players to try other companions)
-items in stores should have higher prices
