I'm currently in 2561, I'd be willing to group. I do play mercy, d.va, tracer, and since Moira came out I'm getting into her but it'd be nice to have some who can either tank or heal for once.
Wow you're at the same SR as I am. And having pretty much the same experience as me too.
I don't know what it is about 2400, but I swear nobody wants to play support or tank. So we end up with one healer (me) and maybe one tank and then 4 DPS that can't hit anything.
I don't play as much as I used to (moved back to Guild Wars 2 due to frustration) but I still squeeze in a couple games a night. I'd be happy to group if you're interested.
