Thank you for your wonderful TA and archery posts.
My TA/archery is 42, and <b>will</b> be my next 50.
What I wanted to ask about is if other people, defenders specifically, seem to be having a damage problem later on. I've heard that mst of the later mobs have some lethal resists. I seem to be hittng very well, just doing bubkes for damage (which would be consistent with resistant mobs). should I just use Disruption and suck it up ?
