I've been playing pretty much only Warrior since 2.3. i103 average with i100 weapon. Have PLD, but can't really comment on it.

Warrior has no noticeable difference since 2.3. 30 points in VIT and I switch between i70 crafted accessories (10 VIT/9 STR per piece) in easier content to full VIT for t6-8.

Someone earlier in thread mentioned losing target for no reason. I'm not sure how it happened for me, but 3x I switched from t8 Dreadguard as target to Avatar instead. This happened completely without my realizing it initially. Could have been I just mistakenly clicked on the screen while doing something else (and Avatar is covering most of screen at that point). Or could be like other person mentioned - though I kind of doubt it.

As for the DPS scaling up agro faster than tanks, that makes sense to me. Actually kind of awesome -- I like for that to matter again. But from what some others have been reporting it was very sudden and coinciding with this patch. So I'm thinking there may be more to it than that.
