Good MMO for PVP?

[Telcontar]

Hello, I would like to ask somebody who triend manyMMOs: What would you recommend to try for PvP? (I know best way is to try alone, but have not so much time anymore to make it to max level in more than 1).

Here are some other informations:
-I prefer b2p or f2p(not pay to win), but if there is something really good p2p I could think about that too.
-I was playing WoW for 5 years only for PvP, mostly battlegrounds, sometimes for entire days. I didnt like arenas so much, only for fun(and points) sometimes. Stopped becouse now I spend less time gaming and with subscription that high, poor character customisation and old graphic it wasnt worth it for me anymore.
-I have GW2, first it looked great, but later it seemed boring to me. In PVE world it was almost same from lvl 1 to endgame and PvP seems to me very chaotic, too much effects, too much fast zergs(for example in WoW times I always prefered slower TBC gameplay over faster WOTLK) + dont like pve/pvp so much separated
-Another thing is, I am solo player(know, funny in massive MP). My friends stopped playing MMO games long time ago, and I am not very social with strangers, so I always soloque and prefer solo-playable characters which can come in and out from fight easily(like rogue)
-Dont care about PvE at all, I do PvE only for levelling and some easy dungeons for basic gear after level cap( becouse of this I am asking you for help, becouse when I look reviews it can have lower ratings becouse of poor PvE which I dont play anyway).
-I like both, classic mmo combat style and active combat too

Thanks for some ideas, sorry for my grammar, dont use formal english until high school
