We would all love it if the game were better, that's for sure. It's human nature to want to perfect something for our enjoyment. So I ask you to name one thing you feel would most benefit this game in your eyes. Please don't treat this like complaint thread. I'll go first.
The lottery aspect of the loot system really gets me down. Why do we have to grind quests for an item we need for our character dozens of times to have a chance? Even though I don't like WoW, I will say this for it, the loot system was good. Even if you have a 1% chance of getting an item you want, the percentage would increase the more you go for it.
I see positives to that as well. It helps eliminate frustration, and possibly helps new people with AH prices. The auction house is a good concept, but the prices are very high for people still on their first character. I suppose the downside might be that it might make rare loot less valuable for those people who are veterans.
