The defense change may affect people. Although, the good solo jobs don't really have any abilities that lower their own defense. (Bst, Dnc, Thf, and I guess Blu and Pup) The raised cRatio cap for 1-handers probably won't affect anyone fighting DC mobs without support, but on EP mobs you might notice a difference.
Oh, right. The EP/DC changes. My bad.
Yeah...I likely won't see any difference myself. I only do EPs w/ pet tanking when on BST and when I go with the wife she's Ochain paladin'ing, so...meh change to me. It seemed kind of bizarre, I wasn't sure what it was meant to change.
