my guild doesn't really know I multibox, and I never bring my guys to raids together -- every week I just do 5x VoA10/25, and 1x Naxx25/Maly25/OS25/Ulduar. If I see anyone with a naxx10/25 saph/KT only pug I might join. I can actually get 4-6 vaults done every tuesday within 90 minutes, and I finish up the other 4-5 over the next few days (both 10 and 25). I don't join voa10 raids unless Im the only one of that class, screw competition I want a monopoly

I find raiding a lot more fun when I can focus 100% on just one character, I can see the fights and explore whats going on and if I die its not that much gold. Plus 5x as many chances to roll on stuff. I've already got T8 and T8.5 on 3 of my characters from Vault, and a few Ulduar items on my mage (guild runs tho so its a bit smoother, up to Mimiron).
