I don't have an inherent problem with things being overly complicated since I enjoy having a certain amount of chaos that prevents combat from getting 'algorithmic'; where you end up with a tidy flowchart approach to 90% of the fights.
I do agree though that with how drastically and rapidly the ground changes in the current game it starts feeling inconsequential as a result. It almost doesn't matter what the current state of the ground is since it will probably change - maybe several times - each turn, and you are almost always able to easily change it yourself, especially with bless that people have mentioned. It lets you "fix" the ground regardless of your class which isn't very exciting.
I've only done one playthrough of the EA so this is just my first impression, but currently there's so much going on on the ground that it ends up feeling like noise that I often tune out.
