Yeah, if it is balance, it's oddly placed. With the limit of one sneak attack per round and a very limited set of conditions where it can be used, capping sneak attacks at 5d6 makes no sense.
I mean, I get it, BG3 combat is really just surviving while Lae'zel runs around and kills everything but, still, Sneak Attack is the signature skill of the class and shouldn't be capped outside of the existing restrictions.
