I just feel like it ruins some of the fun strategic elements. Elemental barrels were cool is os:1, where you might have to throw them around or position them strategically before a fight for a wombo combo. In OS:2 it feel like you don't even need to think about that. It's so easy to turn the battlefield into an elemental wasteland in no time flat.
the addition of 'winged feet' or whatever its called to avoid ground-based hazards is cool, but I still don't care for the aesthetic or mechanics of a battlefield just being an elemental wasteland.
If the effects are to remain as excessive as they are, I'd prefer for them to last for a shorter duration, or for the 'tornado' spell from OS:1 to make a return as a level 1 aerothurge spell to make clearing effects easy.
