well... i also finished the game and i have almost the same remarqs as you have!
The levers don't bother me but the disapointing end did... and what even bothered me me more was those dungeons in the battlefields : you wipe out levels one and two , you go to level three and there you find nothing! no armor... no weapons... not even a boss to kill.. very very disappointing!
At the end of the game i had almost 1.000.000 gold left... and plenty of charms because i was saving them , always hoping to find an item wich could be charmed three or four times... but i never did... i found 1 necklace which could hold 4 charms that's all.
If i compare this with DiabloII... there the merchants ALWAYS had something i wanted... In BD , at the end of the game, I was still using the sandals i found in ACT1 because i never found something better.
Reviewing the enire game : it was a disappointment <img src="/ubbthreads/images/graemlins/disagree.gif" alt="" /> <img src="/ubbthreads/images/graemlins/down.gif" alt="" />
no nice equipment
no bosses
DD is far better than BD
