Simple dou you know why people select tankassasin to pvp because deception tree is assassin has the worst dps all other damage class and if you don't have pocket healer in your group you will die easily or you have to be stealth and heal and stealth and heal yourself without killing anyone in war zones I suggest you go target dummies and test deception dps and compare other dps classes any good ranged class will kill you in 2 or 3 shots in warzones
