I agree, I love the environmental effects and think it adds a lot to the battles. But god damn, I can't even move my characters around without using abilities. Every damn spell makes some kind of huge zone of death or impassibility. Id say lower the area of effect from most spells, and just use a few key ones that have a larger area specifically for the purpose of blocking off areas of the field. And/or give environmental effects like a 3 turn duration
