It would be more sensible for Security Escort to be turned into the equivelent of carriers in space.
You click the button, the escort stay with you until death.
As it is they die in seconds and have a long cooldown, even if you get lucky with the DOFF procs that turn them into a small army. A single spray attack will drop them all.
The ability is just a really lame joke made at the expense of tacticals because everyone knows Redshirts getting slaughtered is Star Trek. Except, an entire class is getting shafted with a useless ability to make the joke.
I find a better solution is the power (looks like an hour glass - forget the name) that gives you two clones of yourself. When not killing the enemy side by side they dance happily whilst awaiting orders.
"The world ain't all sunshine and rainbows. It's a very mean and nasty place and I don't care how tough you are it will beat you to your knees and keep you there permanently if you let it. You, me, or nobody is gonna hit as hard as life. But it ain't about how hard ya hit. It's about how hard you can get hit and keep moving forward." - Rocky Balboa (2006)
