I'm on my lunch break at the moment, so let me detail a few things out about our guild:
1) We used to all be in The Core - we know how to play our classes. Casual doesn't mean NUB PUG raiding. It means we don't make a job out of it, as Deadlyrabbit stated.
2) We have 6 people currently. We have pretty craptastic gear - this is why we want to do some Karazhan.
3) Our main goal is to *gasp*, have fun. I know, you never thought a 5150 member cared about fun, since pro-gaming is our Phase 4398. But it's true.
4) We don't have time to raid every night. Some nights, I get home at 6 EST. Other times, I get home at 9 EST. We usually do what's "available." I go to bed typically at 12 EST.
Our looting system is simple. It's not dkp based - it's basically ran by us. To me, we've all been a part of this community a long time. I won't be biased in loot distribution - it'll probably be discussed by 4-5 of us for about 30 seconds a piece. If you're coming for a specific piece of loot, we don't mind giving it up either first. Our bottom line is PvP, and we really only care about the veterans/MG stuff (for the 6 of us at least). We want to experience the encounter, and build up a larger PvP team to tackle more BGs and win consistently - such as AB/WSG/EotS, and of course, Arena.
Please PLEASE do not ask to join if you're looking for a HARDCORE or even a "STEADY" raiding guild. If you're looking for lots of PvE items, please don't join - not because we won't give it to you, but because we're not going to devote hours upon hours of raid wipes to learn super hard content while maintaining DKP and all that shit.
What we're looking for is as follows:
1) People who like to PvP and WIN at it.
2) People who don't care much about PvE items but want to experience it like we do. People who won't cry about wiping or cry about us stopping for the night due to repeated wiping because of a) tiredness, b) lack of motivation, c) pve sucks.
3) People who have thin skin. Yes, we abuse each other constantly on ventrilo and such. If you can't handle a couple of mom jokes, vivrant on the guild is NOT for you!
4) People who won't cry about a few losses due to us all still using greens and having 4000 less HP than the MG arena/pvpers.
