I have a groovy and wonderful guild. The night before, we ran the Ring of Blood to get me the Battle Mage's Baton.
I had 5/6 shards, and Grimm had 3/3 dragon scales, but I didn't have the potions, ore, or arcanite.
My lovely guildies pitched in with deposits to the guild bank and holding their entrance into Dire Maul for almost an hour while I got my demonic stuff together.
Once in, it went well. We had 2 level 70 locks and one level 60, plus a pally and a shammy, and we got everything we needed between the five of us.
Yes, I already had an epic mount. But this is a matter of pride. A warlock without a demonic mount that has a flaming mane is just a mage that like demons a lot.
Out of grattitude, I've dropped 100 gold into the guild bank and my next 100 is for that as well. It's the least I can do.
