I am actually using the /sit command pretty often in PvP. For quite a time even
It has no chat message linked to the emote. So on a Interrupt/Damage Ranger I tend to run forth and /sit + cancel at chokepoints. You would be surprised how many ppl suddenly start to c+space wand you (especially casters) thinking you are a trapper. Gives my team at least 2-4 seconds time to set real traps/prepare spikes or whatever you want to do before the surprising moment is over. 2-4 seconds is a lot of time actually. I hope I am not the only one doing this or I'd feel pretty stupid

. I know it sounds stupid but thanks to several FOTMs a lot of ppl watch for trappper-like animations on a Ranger.
