I agree completely with making it as close to 5e as possible. Remove the freebie bonus actions, make only the bigboy spells like fireball create surfaces (or those that specifically do it RAW), remove like 80% of the oil barrels, make reactions usable, and it will be an actual D&D 5e game. So far it feels like they took Divinity, which was great don't get me wrong, and decided to reuse half their stuff in a completely different context that doesn't really work. After going "wow, let's make jumping and pushing the core mechanic of the game".
