I don't think 3v3v3 is a good idea.
I'd prefer 4v4v4, and each player in each team must be a different class. 1 DK, 1 Temp, 1 NB, 1 Sorc.
Ruze is a veteran of the PC Beta, lived through the year one drought, survived the buy-to-play conversion, and has stepped foot in the hells known as Craglorn. He mained a nightlbade when nightblades weren't good, and has never worn a robe. He converted from PC during the console betas, and hasn't regretted it a moment since.
He'd rank ESO:TU (in it's current state) a 4.8 out of 5, loving the game almost entirely.
