Hi there. I'm a lvl 70 warden. I play wd/w as my primary character. I switched over from scout after chapter 3. I'm pretty sure I'm the only real end game warden tank on my server. Lol. Let me give you my stats first.
HP: 160k +\-
def: 375k (15min buffs) 730k (short buffs)
PA: 50k +\-
Now keep in mind that since I switched from scout, I still have 3 items that are scout statted. I still use a scouts unicorn chest with all dex/pa stats. Lol. Anyway I have some pretty impressive numbers even with those items. what I've found is that I have more than enough PA. I typically stat like 3 stam/def 1 stam/hp and 2 stam/pa
With these new stats I'm going to try it a little different. I'm going to try 4 stam/def 1 hp/def and 1 stam/pa. Since warden has 4 solid aggro skills I don't really have to worry about aggro too much. These are just my opinions. No flaming please.
