The combat in original sin and original sin 2 never became tediously long. So i expect the combat in BG3 to follow a similar path, interesting, chaotic and brief encounters.
Combat in real time with pause was likely artificially lengthened so the combat wasn't over too quickly.
Speak for yourself. I found combat in D:OS extremely tedious and boring and repetitive and stupid, so much so that I eventually learned to just lower the difficulty all the way down just before a combat started so that I could breeze through it as quickly as possible to minimize my boredom.
