That would be fine as far as being invisible. And, I don't look at the Blade Dancer for being invisible any way. I look at it for the Blink ability combined with the speed, plus arc grenade to chain lightning to enemies. As for the Grenade, I understand the weapon tactical combo. My point is that the Titan Flash Grenade or Pulse Grenade, and the Warlocks Vortex Grenade can be used in the same scenario as a swarm grenade but with more effect. The thing I like about Swarm Grenade is the tracer ability. If you throw it into a tight, dark room, the grenade will find the enemies so you know where they are camping. That makes it useful. Same with Incendiary Grenade. You can catch them on fire, and see where the damage numbers are coming from to see enemies around corners. My point however is that the other grenades are more powerful in general. Take 6 guardians and put them in a room together bunched up. Throw any Hunter GunSlinger Grenade and you wont kill a single one without shooting. Do the same thing with a Titan Pulse Grenade or a Warlocks Vortex Grenade and you kill all of them. I know no one bunches up like that. I get that. My point is the DPS capability of the other grenade types.
