So im a sorcerer and marauder who like to pvp a lot(wz)

i use to be a rogue in wow and i read about the nerf operative got but if i work hard on my caracter and im use to pvp (wz) can it still be a good choice or the nerf destroy that class( for pvp purpose)

Nah ops are fine.

Especially with Slip Away, you're deadly.... every 30 seconds stunlock..

I can kill someone in less than 10 seconds if I get the opener off... 15 if I don't...

There are several things you have to understand. First, Ops are a poorly designed class, and that's where most of the problems stem from. Ops are basically the Druid/Paladin from vanilla WoW, basically the class that seemed like the devs just slapped together in five minutes. Second, most of Op's good abilities are learned late. Hidden Strike is at level 36, Acid Blade at 40. Meaning until then, your damage output pales in comparison to later on which may cause a lot of early struggles.

That said, it's still possible to do very well, you just have to work a little harder. After a lot of practice and a lot of sucking, I now usually rank among the top in damage, kills, medals, and least deaths (10 to 49 bracket, not quite 50 yet). If you find the class fun, I say go for it.
