Another update: That DK spot is still open. I just want to clarify something regarding the sort of app we're looking for, so that people don't waste their time. I'm not really looking for someone who will be on the same level as most of our current players. I already have reliable options that meet that threshold.
I'm looking for someone who will be better than the majority of our players, with application credentials that make that fact very evident. That means some or all of the following:
Top-50 pre-nerf M'uru/Kil'Jaeden kills
Gladiator-level PvP experience
Main tank experience and/or raid-leading experience in one or more competitive progression-oriented guilds
Outstanding DPS (6k+ on Patchwerk) on a consistent basis, with whatever the top spec/gear/glyph setup at the time has been.
If I'm not going to immediately see that from reading your app, it's honestly best not to bother. We don't do trial invites, or anything like that -- I need to be able to know as a matter of certainty that you are one of the best players out there simply by reading your application. I don't mean to be condescending or dismissive in saying that. I'm just being honest, and I don't want people to invest time in composing an app only to be disappointed.
