There is always a difference in opinion and who knows, this may have been mentioned already on all of these pages. However that being said, I absolutely despise trash that just falls over, dies quick. I enjoy trash that takes much longer than that and allows certain specs to unfold their true potential, specs that have a ramp up time like affliction warlocks are utterly useless in situations where by the time the last mob in a group was dotted, the first is already dead and with a little bit of luck a shadow bolt may or may not be cast fully, it may even reach the mob in time before it dies AND it may even deal damage before it dies.
It's just not fun to me in those super situations.
But then again, fun is very subjective and at the end of the day you can't please them all.
