No chests in MrT, and that's just fine with Blizz

Here's something that didn't really hit me on the first few times through Magisters' Terrace: there are no loot chests in the instance. Eleste of Frostwolf asks why, but Drysc only answers "why not" -- apparently Blizzard isn't too bothered that the only loot to be found in the instance is on dead mobs.

Which isn't exactly new -- not only are chests open to many exploits, but Blizzard has slowly been taking steps away from putting random caches of loot out there for anyone to grab. In the last patch, they even made it so that chest loot gets rolled on, so it's probably a fair guess to say that most loot chests are on their way out of the game.

They weren't in there for no reason -- Blizzard wanted to make it so that after toppling a group of mobs, you could be lucky enough to spot an extra stash of loot to grab all for yourself (not to mention that they give Rogues something else to do in instances). But apparently the problems of loot chests outweigh the positives, and it's probably true that MrT is a preview of Wrath -- loot chests are going to be rarer than ever.
