Ow yeah something I'd as well enjoy queueing for duties where i can say DF tell me what to use out of let's say PLD/BRD/WHM and i do the duty in the role that pops because i main Tanks/Heals but wouldnt mind to DPS stuff if i can speed up DFs that way (its rare but happens :P).
And yes we did some derpraids (stoning each other on purpose and killing some other ways can be such a fun <3) in T7 with static where actually noone besides me was in a mainclass (I had to because noone else felt like healing that day) and it is pretty fun think we can take the choose classes for others over though some of us still use it as a way to obtain some of this daomed light but well...
