PvP in this game is a joke.
It's ''arena'' pvp for kids and/or other simpletons.
If you want real pvp; go to a game that has open world pvp (like LOTRO once had, untill Turbine [now Standing Stone] completely ruined it.), where you can fight Raid vs. Raid or have big open brawls.
Now on SF you have west-coast trash who's mommy told them they are a special little boy/girl one time too many, being very toxic; shaming/naming ect. while running around like complete and utter morons, thinking that everyone logged in, because they are playing (I mean; omg.... lol!).
I've played on every server and I recognize the type even some names from former; Bastion, Begeren and Harbinger
I mainly played there sometimes, just to have a laugh (It was a miracle when you completed a FP/WZ with your original group, not to mention finish it at all. Within 30 sec's they were at eachother's throats, it was hilarious).
I could go on..... but... meh.
My humble advice;
for Granked: find a team , people you can rely on and can ''train'' with.
for Solo Ranked: take it as it comes and laugh at the toxic halfwits.
I've played many games and this one on the side, so in that sense; You think this is toxic? You should've seen World of Tanks at it's prime.
These are just prissy little princesses, throwing hissy fits, they're a joke and somewhat adorable at best.
It's PvP: you win... you lose... learn to accept that, but always try to get the win.
