Need to change of Class

Hey every one!!!! Well I'm tired of reforging and changing stats on my Warlock, well this class doesn't have no future on Neltahtion, it's sad cos I thought it would'nt so boring to have it, but dps wont let me meet on Madness HC. So I was wondering it's possible to do class change, and if it's posible, can I keep the tier I bought with tokens from DS, professions and ítems on bags?.

Hope some one can help me.

U can't change class. And thats bullshet that lock dps wont let u go for dw hc. Personally i enjoy affi back on retail and luk dps was decent. I suggest improve urself as lock or make new char.
