Hi, I'm wanting to buy the Saronite and 1 Light achievements in 10 man Ulduar since i cannot find groups for this stuff. I have all other achievements + Algalon just have those 2 left.
I am Exp in this fights and have decent gear (Unholy DK) so you wouldn't be carrying me.

Is it at all possible to just chuck me in for these two or do i have to do pay for a full Ulduar 10 run?

I'm afraid we can't offer much of a discount on the price. We run 3 people every Friday around 7/8 server time, spots in the group are reserved in the order that people commit.
