Just to set this straight. That was one of the worst, if not the worst raid rift we have ever done. There are a lot of bugs and we didn't actually know what was going on, not to mention half pug raid.
We normally have organized groups.
On the topic of raiding, we have a semi-core raid group and there are a lot of rogues at the moment so there will sometimes be open spots but a raid spot is NOT GUARANTEED. If you are accepted please don't feel like we have something against you if you aren't invited to raids. It is just that some people seem to feel left out when they aren't invited.
In saying that, the raid requirements for a spot are full t2 gear and 200+ hit.
Raiding is obviously not the only thing we do in the guild, quite a few people often run warfronts and T2 instances so you will always be able to find something to do.
Good Luck with your application
