Well, whilst I had a period as the MT and was distinctly the best geared tank, that's passed, the wars have caught up with me:

I've been passing loot, quite a lot, and bidding reasonable amounts as not to muscle the wars outta DKP (read: If I do overbid them and I am gonna pass: they get it for what they bid for it, etc).
Finally within the last few weeks the wars have caught up with me (Tanks as Ashran/Nick), and whereas the difference was noticeable but not critical before there is no noticeable difference now.
I've been encouraging them and teaching them as best I can, but the guild is genuinely well educated, some of our members are easily of the level of the best theorycrafters here, but for their own classes.
A few are multi-class knowledgeable on a communal level.
I don't campaign for my spot, haven't in a long time.
Every time I skip a raid the guild goes emo, BT or Hyjal ;\
Edit: And since I took up tanking all I am is a support RL ^^
