What's the purpose of mez protection? I'd say the purpose is to keep you in the fight. And anything short of an EB or AV (I have killed many bosses while mezzed) is short work even with T1 and T2 attacks. I couldn't imagine skipping either one or short slotting them; unless its the Secondary T1, those are still pretty worthless. Blasters have a tool in their toolbox for dealing with mez, use it or don't use it.
