Merely changing droprates and rolls doesn't fix this. Some core problems are;
- Item stats are rediculous compared to character stats. Your base main stat at lvl 60/0 is 187, yet goes up to 2K+ with equiped gear. This pretty much fully negates your character level. In fact, why not simply remove it?
- Life vs damage dealt is completely off. Players deal multiple times their own life pool in damage, while monsters deal only a fraction of their life pool in damage. This seems irrelevant, but is the core reason why things like reflected damage and thorns are so utterly broken.
- Everything is random, to the point (as mentioned) where class specific items roll off-stat bonusses. There is no point to this other than increasing the value of good items beyond even the price of the game itself, which is rediculous.
- You can't purposefully craft anything or change almost usable items to actually usable ones via crafting. Stuff is either good, or trash.
- That we farm has been taken for granted, and has been calculated into every aspect of this game rather than viewing farming as a result of acceptable odds. These odds have been divided over all players combined, with the AH as a required mechanism to obtain any usable items. You find nothing for a reason (and incidently this is the same reason why there is no offline play).
- You can buy your way to the end, but then there's nothing left to do. This makes perfect sense, because the fun part is working your way to the end, not getting there.
In short; there is nothing to do but farm, and hope. I honestly don't think this is a bad game, I just believe that it could have been so much better, more fun, and could (and should) have lasted longer.
As disappointed as I am in this game; I'm also sorry for the artists and developers at Blizzard that put all their love and time in making this game possible, only to see it destroyed by bad choices that could so easily be fixed, if only it weren't for headstrong marketeers and corporate politics.
