I've been doing a lot of skirmish recently and played a game against 3 blade dancers on Pantheon. I was hanging alone around the middle when an enemy jumped on top of the cube thing and activated his arc blade. I panicked and tried to jump backwards on to the ledge where the heavy ammo spawns and completely overshot it and went right off the map. On the bright side...the bladedancer lunged at me and went off too; that gave me an idea. Since this was only skirmish and suicides neither give/lose points, every time we heard a bladedancer and there were no other enemies close by to tag us, all 3 of us would find the closest cliff and jump off, wasting their super. Most of the time, they would sit there and dance or teabag after we jump, but at least they didn't get the kills. We've had a lot of success doing this, and on that one Pantheon game, the enemy team used their arc blades 5 different times and achieved a grand total of zero kills with them (although someone shot me with a last word bullet one of those times and got the assisted suicide). It's a pretty scrubby move, but gets a big laugh every time, and even the enemy team caught of and started jumping off too when they heard our own arc blades or golden guns activate.
