HAHAHAHA that video is hilarious!
As I said, it shows how screwed up Larians combat system is, but I doubt they will change it because its their special snowflake thing they want to advertise.
Think that's a little on the extreme. I think it's fair to say this kinda stuff will most definitely be fixed.
That said I agree with Tuco, I don't need levels, though i am happy enough if players want the option in settings totoggle them on/off. As for finding out like i ye olden days. I mean I killed the Ankheg bugs on the farm in BG1 at level 2 and Drizzt shortly after. Oh many a reset and playing with necromancy etc for extra bodies, but it was fun and the rewards were massive. However due to the RtwP nature of it, it was fast, so failure didn't cost you an hour, hence I could see why some form of indicator might for some be helpful.
