I'm currently looking for partners, and I have decent experience on 2 chars:

1) Warlock
Spec: Usually SL/SL, but very experienced in UA and Felguard specs too.
Experience: I've been playing actively since arenas came out.
2v2 - Awarded Gladiator in Season 2 @ 2300 rating (with a partner on 56k mind you)
3v3 - Played in the 2000-2100 range in Season 2, but no teams yet in Season 3
5v5 - Played in the 2100-2200 range in Season 1 and 2, but only 1800-1950 in Season 3

2) Priest
Spec: Disc
Experience: Started a few weeks into Season 2
2v2 - Highest rating reached was 2100 with a Feral Druid partner in Season 2. (I know, it's all I could really find.)
3v3 - RMP up to 1900 in Season 3.
5v5 - Played in the 1800-1950 range in Season 3.


I haven't exactly had pick of the litter when it comes to pvp partners on my server, as you can tell from the Feral Druid and 56k guy being my top 2v2 partners. I think I have alot more potential if anyone's interested!
