Speed Run + Timer

[Matsume]

There should be an all mobs vanquished achievement for every dungeon. That way there is a reason to slow down and return to a dungeon.

This is quite possibly the best idea proposed in all threads complaining about speed runs being linked to loot.

SE could implement conflicting coffer requisites that make it so all coffers cannot be obtained in 1 run; for ex:

Normal run = 3/5 coffers from boss
Speed Run = 4/5 coffers from boss
All Mobs run = 4/5 coffers from boss

the catch is that the speed run chest cannot be obtained by doing an all mobs run (because there isn't enough time to kill all mobs while doing a speed run) and vice versa; the all mobs run pops a chest that cannot be obtained by speed run but in turn does not pop the speed run chest.

This way people will have reason to do both speed runs and non speed, but all mob, runs in order to get all the loot. It would then be logical to split up the darklight or whatever other gear between those two chests.
