Oh, I fully understand how threat works and how not to pull it. I do not need to read 50 posts about it to have a valid opinion (answer), but I did anyways. Would I like a threat dump? Sure, why not. Do I need one? Nope. Why? Because I do not blast OBs while the tank is situating the boss. After that boss is positioned there is no way for me to pull off of a vengeance stacked tank that is doing their job.
It sounds like you must play with some horrid tanks or you do not let them get aggro. If you really have it that bad, get a pally to toss salvs your way. Somebody has to benefit from that spell now
I wonder if the top parsing frost or warriors ever complain about threat? Nope. You are not putting out more damage than them.
Yep, that is it. Absolutely a L2P issue.
