Took some time get these to work and they are perfect for certain situations:

/ac "Cover" <p#> # is 1-4 of party member generally a melee class. Will have manually change each dungeon in macro menu.
/ac "Cover" <st> This will help if your healer gets agro for any reason it will target thru the mob to the mobs target I.e. the healer

These work great for PC and PS3 since you don't have to take the time to target and use. You just use them.

trying some advanced target to bind effects for maximum threat on multiple mobs at once.
