I have never had a problem with hate on glad before. Provoke II, taunt, and War Drum pretty much can keep 2-3 mobs attention at once on me. If an archer does a 1500dmg regiment ws or something then yea I am losing hate probably but that should be expected.

When I tank I usually do not DD much at all. This is pretty much my cycle.

Throwing to pull => provoke (taunt as well if it is more the 1 mob/wardrum if 3+)=> aegis boon II => a few swings => taunt (wardrum if it is 2 mobs) => Deflection or what every the 50 shield skill is=> a few swings => sentinel => provoke/taunt => then repeat at Aegis boon. Note that I rarely get though a cycle unless we are fighting multiple mobs at once.

I think it makes tanking sorta interesting, you have to gauge hate, timers, as well stamina.
