Diablo 3 is fundamentally broken

[FoxBat]

However, there should be more randomized, non-quest vital, caves/dungeons that provide a guaranteed elite pack and a nice chest at the end to compensate for those that want to do a full clear. D2 had many, D3 has a few, but there could be more extra areas for those that don't want to run past everything.

D3 actually has a ton of such areas. (Check out the dungeon map achievements.) The only problem is that most of them don't spawn in a single game.
