I don't KQ too much anymore, but from what I remember the lack of fighter tankers in Teva isn't too big of a problem. With a few good clerics to back up and scrolls applied to everyone, it seems like anyone can tank. A lot of the kqs I participated in had clanks/manks/tarchers, and it worked really well. I'm not overly fickle about who tanks; if someone attracts aggro, is able to keep it, and can survive, that works for me.
I don't blame fighters for not being able to tank as long as they have the will to tank. I hate it when fighters decide they can't take on whatever we're fighting and sulk in a corner. Be useful! If you can't tank, be a DD or something. At least contribute. Stun is a godsend, use it! Even if you're upset, pretend you're taking the damage and just slash away :>
