Re: Questions on Warden Tanking
I got a bit burnt out on my warden in the upper 50s from trying to grind deeds so I can't comment from direct experience in the higher instances.
I do seem to recall people saying that the threat component of Piercing Blow still works on the brutes when blood pact is up.
I'm sure others can comment on specific rotations for a place like SG, but I tend to think it depends on the group. If you have a champ or others using AoEs you might need to start out with a masteried Defiant Challenge for the forced attack, or Exultation of Battle. Conviction has a threat transfer to it so I would use that once things are more under control.
If you can get your fellowship to let you ambush / run in first and get off an aoe threat gambit before they unleash, it will help you get a head start. Otherwise you might have to spam Piercing Blow and switch targets to stay in the lead.
As far as traits go a lot of people like to trait 5 shield plus the capstone for the increased hot pulses and survivability.
