This is a bad time right now to be doing much of anything in WoW. The PVP system is going to be overhauled in the next few weeks, so your progress there will be minimal. Raiding is sort of sucky right now because simple quest blues in the expansion will outclass the raiding gear you spent hundreds of gold and dozens of hours wiping on. And there will be an excuse to reroll one of the new races when the expansion comes out.
I just PVP and casually raid now, and for me, getting to rank 13 was easier than maintaining a hardcore raid schedule. I could pick and choose when I wanted to be on. If I want to go out Friday night, I could make up my honor some other time during the week. You don't have that sort of freedom in a raid guild that requires 80% attendance or something. I'm really looking forward to the PVP revamp because there will be a lot more for me to work toward, on my own schedule and at my own pace. I don't have to raid from 5PM - 1AM Wed,Fri,Sun or whatever
Come back when things in-game have settled down a bit, but stay out for now.
