Hiya Callahan,
I wanted to write and commend you on your writeup for the insane in the mebrane achievement, it's really detailed and impressive, and I think I will be going for it on my achieve hunter, slowly, though I can't imagine I'll be able to afford all those decks for a very long time!
I also wanted to point out a possible mistake, tiny thing but just confused me for a sec:
'The other option is to turn in Darkmoon Decks for 350 reputation for nonhumans, and 285 for humans' - I expect you mean 385 for humans?
That is all from me, thanks a lot for taking the time to write the guide for us little people :)
Cheers,
Max
