As for combat in any RPG and D&D in particular, the D&D rule set is not very engaging, 5e classes are built to have 2 or 3 tricks with most mobs designed to work around them. Combat in Dragon Age: Origins was the best of that series but combat became little more than a weird combo system, with little choice on your end as to how you 'solve the puzzle' of an encounter.
So far in the BG:3 EA, I'm pretty satisfied by the combat so far, with the caveat that from first level to fourth you haven't really hit the levels in D&D that turn your characters into superhuman death dealers. There's a reason E6 Rules where a thing.
