I know that the devs are really busy and this will be extremely low priority but it would kinda fun if there were taunts based on your class/prestige/destiny etc. /tauntp would make you perform a taunt that is uniquely available to your prestige class. For instance a fire savant can start juggling fire. A Frenzied berzerker could go crazy and start smashing stuff etc. etc.
Again very low priority but I think it would be kinda fun while waiting for a raid to showoff your unique taunts etc.
