In the first version of the EA I managed to beat them second try in a relatively fair way. (Shoving them down the bridge, else just using attacks, spells and items).
When the game is released we can be at least lv5 when we get there (another attack for martial classes, lv3 spells, better cantrips just to name a few things)
So I think the fight is OK as it is.
Plus the fight is optional. There are other ways to proceed to the next chapter.
As a completionist I will definitely try to clear the whole map before I continue, no matter if I continue this path or another one.
