I have considered a pvp only team.. and my choice is 5 shadow priest... main reason is... 5 SP will kill as fast as 5 locks.. BUT.. they can rez.. if you have ever had to run 1 toon back while the other 4 stand around... rezzing is a big thing for me otherwise iw ould have 5 hunters...

BTW... im more scared of 5 sp than i am of warlocks.. it hink its instinct from pre-bc face melting
