I get the allure of Clearing an instance fast, I understand it's of course more desirable to finish an event in 20 minutes as opposed to 45. Here is what I don't get: why give the community another excuse to take a warrior tank over a paladin? Don't they have enough? I'm ok with having two tanking styles, but Seriously if I get thumbed over for a warrior because the odds of getting a 5th chest are much better (because of faster kills) something's not right. Sure it can be done with paladin, but it can be done routinely with a warrior.
Get rid of this 'speed run' drop please, I'd much rather have a 5th chest for killing all monsters in the zone instead.
