Jumping around other message boards, I realized I wasn’t the only one that was (very) disappointed that there were only 4 acts, I know the battlefields are meant to take up 1/2 the game time, but some people (like me) just got tired of the battlefields or were not interested to begin with, and honestly even with super grand battlefields that everyone would like, this game could still use another chapter IMO, one in the home world would be nice to provide a change of scenery after that long trek via Nemsis.
Any way, why not make a free expansion with an extra act, Icewind dale had one, and I feel BD is too short if you ignore/have no interest in the battlefields.
