Right now, you could just send queuestance and stance together. If you're off balance/eq, queuestance will kick in, if not, stance will. Then there's that abysmally small percentage of cases where you may regain or lose balance/eq just in between the the arrival of the two commands, which may invalidate both, but that's bearable, I'd say. I'm rather indifferent towards the OP suggestion myself.

Honestly don't care much either way myself, it's just the trying to claim that one simple if statement in the client will fix everything that's bothering me.

If I understand correctly, the only reason the queuestance syntax was added was for monks to use in the middle of a series of forms. In my opinion, that should be the only use for the command, as there's no real need for anyone else to be queueing up a stance.
