So i've been leveling my toons up they are all 44-45, but i have my bro's two accounts and my wife's 2 and my 3 so total i have 7, which i've been slowly leveling them all and so far i have:

1x Warrior, 1x Pally, 1x Priest, 2x Mage, and 2x Warlock

I am tired of leveling 7 toons with groups of 3 and 4 and want to get a core group of 5 going, what do you guys think i should keep out of the 7? The warrior is easier to tank with for me at lvl 45 cause the pally dosen't have avengers shield, and he breaks sheeps with his concencrate, but i've heard pallys are better in endgame to tank with, or i could drop the priest and keep the pally as a healer. Any suggestions would be appriciated
