I can't make this decision for you.....it is a case by case basis. If you are geared for some PvP, I think it would be slightly less painful. If you are wearing all PvP gear, then perhaps what you need is a little bit of self inflicted S&M.
PvP is not quite like riding a bike. I stopped PvPing for the most part when I let my Warlock collect dust for several months during the expansion. I did well before, shouldnt I do well now? NO, NO I SHOULDN'T. New PvP spec plus no PvP gear equals OWNED. It is more like knowing how to ride a bike, then when you come back to said bike, you find out that it is now helicopter.....that hates you. Think Night Rider....only as a helicopter.....with an attitude like Bill O'Reilly.
Beside all of the pain and torture, there are some nice parts to PvP. If you enjoy shattering people hopes and dreams one killing blow at a time. If you do, you would be a GREAT in-law. There are times when you will feel almost invincible (especially depending on the class). Unfortunately, I am not a rogue or a death knight. I am a Warlock. Being a Warlock consists of hiding in the back and hoping that Rogues and Death Knight dont notice you conflagrating their faces off. Because if they do, you will soon be treated to the tilt o whirl that is melee PvP.
The tilt o whirl of melee PvP is when the bastards run in dizzying circles around your ass so that you cant target them. It is the single most irritating thing in the game, especially when you are stunned and slowed and there is a rogue sticking a rolling pin up your ass.
I do it for the challenge.....and I am not a fan of punching myself in the junk......not that there is anything wrong with that. If you are running some BGs in the reckoning group and you see a Warlock named Theladon melting faces, feel free to say hello.....or kek while you are killing me if you are a horde.
