Very glad I backed this too. I was already please with the alpha version of the game, but the beta now looks like the game will hold all of its promises (if not for schedules, but we're over this now).
Among all the complaints and (often valid) criticism of the current mechanics, I'd just also like to step in to say I really like the design philosophy behind all the systems in the game, even though some might need some more fine-tuning. Combat challenge, item degradation, status effects, general difficulty, all of these look very good to me.
Congratulations to Larian, already, on making the most exciting rpg released in these last, what... 15 years ?
