the first would certainly be TR.

TMO and Ascension, in my experience, will shoot off and snag a dragon here and there. They ebb and flow depending on a somewhat fickle guild morale.

Divinity can be counted on for a solid dragon kill or two every time there is a simultaneous server respawn (of which there have been many as of late, and i heartily enjoy because it is a strategic battle while also letting everyone have a part of the bosses) -- they're good peeps too.

these are, of course, my personal observations -- full disclosure, again, i'm an officer in TR.
