The Dimensionalty is kinda important. Agreed. For the Shatter spell we acutally see a sphere. Fireball really seems to be 2D.
Camping is awkward.
That system was developed for PnP...in this game it feels really off to me. That would have been something to think about. But Larian rather does changed like shove and jump, which ruin the combat balance. Or puts a lot of effort in utilizing strange ground effects and even creating items for that...Electrified water is HORRIBLE to look at.
