Seems like a waste to actually pick it for quests, bonus objectives, mats farming or anything of the sort. Ramp up is just way too slow for it to ever catch up to FF & BP. Seems like it's only useful for raids in theory because even in heroics it's just bad.
Defile still seems to be the best out there.
Thoughts? Think they should reduce # of stacks to 5-8-10 perhaps?
