Random guy looking for GvG guild

So I am only glad 1, and trying for 2 weeks to do my way into higher forms of pvp. I joined new guilds, left new guilds, joined pve guilds that said doing gvg ... Well I tryed alot of things, including having a better glad rank or a HA rank to be able to get into better (or real ?) guilds .........

But I found out that it was useless without a higher rank. That's why now I'm trying to find a guild here

Now the little story. I started out GW with a Mesmer, finished all 4 games with her. After that, I started pvp. I did AB (joined AB guilds) and RA mostly. I did my glad in RA mostly with R/Mo templates and, when I found out that it was playable (in korean district), PB mesmer.
I tryed lots of builds (I think there are few mesmer builds I haven't tryed out), made 4-6 points with A and W.

So I think I could play any of those classes. Or any other class, just need to try it in action, except Monk and Necro (can't bear playing necro).

So so so ... As I have little experience in 8v8 (and as I can't get to talk and get advices from skilled players) you'll just have to tell me what I have to do (and I'll do it right), just little advices on the gameplay.

Ranks and balths are : Luxon r6, Kurzick r2, Glad r1, around 1 million balth points. I am speaking English and French, and I can be on from 20h30 to 22h every day (I think i'll be on more, like saturdays when I'll just go to sleep at 3-4am) GMT +1.

Thanks for reading, and if you're a mesmer and your guild doesn't want me, do not hesitate to give me advices
