the old x5 multiplicator would be enough.
as for pdef, we all should remember that wardens cannot wear shields, and a Talisman is not a viable option because they only have more damage on 2H weapons.
Just take a Annelia right hand + Shield master + Enhanced Armor combined , thats a lot of pdef even without 6x139,2 Stamina on the item Warden buffs have to compensate for because they cannot wear a shield.
Right. Dropping down to a 1H weapon would cut down a lot of aggro (due to lesser damage aggro) even though you would be more survivable. Still, with the type of gearing that's going on, I wouldn't be surprised to see someone pull off a 1h Axe + Talisman Wd/W combo that could still hold aggro and be even more survivable with the off hand stats.
===================
I fully support Knights getting a passive ability that would add +% Aggro generation to all damage skills. Having a knight in group (in my opinion) should guarantee lockdown in aggro and taunt for that knight. DPS guarantee DPS, healers guarantee heals, so tanks should be able to guarantee tanking.
