try looking into mercurios 2 step macros... I havent played a lock properly since Season 3, I have 2 locks in one of my grps and just use 2 step macro

Im trying to get my gf to start boxing tanks...then i think we will run our own 10 mans. : )
ahhah my fiance his main is prot pally, so 1 tank is great as I handle the dps and heals... though I was thinking of the same thing, to get him to 2 box tanks and maybe a healer or 3 so we can do our own 10 mans between us for fun of it.
