I saw a comment or two about mashing CA's with buckler spec.
I think thats completely wrong. A good chunk of your dps comes from your autoattack.
I only have legendary SoD, and i use a crappy buckler [still waiting for Howler to drop

]
but i can do between 1.2k-1.9k [closer to 1.2k without dirge]
But the way i work it is, i do /weapon to see what my adjusted attack speed is on my wep, and then i time it, if its roughly 2seconds+ then i queue 2 combat arts, let them execute, then wait a split second to let my autoattack hit, then queue two more... thats withouy any attack speed buffs
But! when im MT, my delay is significantly lower, so i only use one CA at a time, before letting auto attack go off, then i hit another CA. Thats how it works best for me, dunno about anyone else.
[P.S.: Buckler = 60% Double attack for ur auto attack, thts huge, and another 9% from Guardian tree, and then 3% from Strongbear bonus effects [for 3 pieces] when i dont need my best gear on]]
