So I want to try and to and make a Pally + 4 Shammy team,

Would this be good for heroics in PVE, like SL and such? or should I got 5 shammies? I'm also looking at 5 Warlocks, or 4 locks and 1 priest

Also I'm confused as to how I can control both the pally and shammies, do I just put the pally keys in and then keep those blank on the shammies and then put the shammy keys in where the pally doesnt have keys?

Anyway of getting this keymap, with the shammie keys to show up on the main screen of the pally? or will i have to get a printout or memorize?

Thanks guys, I'd really like to give this a try once I get somemore free time
