It depends what you mean by good at pvp.
If you mean you want to become a good dueler and sit on wrong roof all day flexing your epeen then a few months of just dueling people.
If you want to become a good field fighter in a group then maybe a couple weeks if you have a good target caller calling the fight.
When I get back to the States, I am F***king calling our fights. I am tired of you and Dubar's flakey calling.
I shall give you an example of my perfected calling:
-Dorinda calling -"Explosion up, I got curse, Target name + racial slur, Now."
Vent responses after a perfect synch (due to perfect calling.)
Dorinda's response: "lol, scrub." "Did Lynk hold his spells?"
Lynk's response: "How does she call like that, I am in awe." "DUBAR, DUBAR! I got the killshot, I hold my spells."
Dubar's reponse: "good call!." "lynk, stop holding your spells."
Joo's response: "[Insert racial slur], lol." "Who guilded lynk?"
Big K's response: "Can't handle Big K."
Kincade's response (In a british accent) "WOW! F**king archer."
