What I want
-The way loot and the stats on loot worked in DD1. A lot of people talk about the negative rolls, where some stats are negative and others are positive. I really like this. DD2 gear felt really bland and boring to me.
-More customization for heroes. I liked character creation in DD1 with 3 colors to color your character. A thing I want is the option to change the character's gender. In DD1 the 4 main heroes and the 4 heroes of the opposite gender had the same buildings and similar abilities. In DDA it would make more sense to have them be the same hero. The Summoner and Ev had skins of the opposite "gender". Maybe its better to call them "masculine" and "feminine", because summoner is some sort of dark force in a robe and EV is, well, a robot. It would be cool to see a female barbarian as well. The female/male could then have different skins or the same skins but different looks to match the gender.
-A lot more useful accessories. In DD1 endgame you only see accessories from a few different maps. You see everybody with the same beard and tophat. I think this could be improved by having accessories drop with random colors(a lot of different colors, in arcane library you can get glasses in the different colors, red, yellow, green). And a bigger pool of accs for each map. Accessories are supposed to add detail to your character while also having good stats. It would be fun to try to get that orange cowboy hat to match your orange bracers. With your orange pet monkey, ofcourse. More color variation please!
