It's already banned at the moment you said free eject warp plasma.
It's power far exceeds that of the borg console which is what I guage to be the best upper limit console allowed for shuttle wars. And it definitely by that same virtue exceeds the 1 tac console on a shuttle. So you could just roll both, a borg and this.
But no one knows exactly what the power does yet! It could be completely useless aside from the slow/engine shut down.
We'd have to wait and see.
It's a free extra tractor beam at the minimum. Just imagine a Flyer with Tractor beam, and this. At the mere cost of a console slot? Yes please. It's stronger already than a borg console would be and the borg console is stronger than the friggin sci consoles you can use.
Slowing and stopping engines alone is exceedingly powerful in shuttle wars. As I imagine it's an AOE this makes it even more powerful than tractor beam.
The whole reason I host shuttle wars is for everyone to sit down have fun and get away from the Cstore Spamfest known as pvp for abit. I'm not going to start allowing that kind of non sense in. I might as well let AMS in while I'm at it too then if I'm going to let this in. Or Theta Radiation... or god knows what else. No.
I think that is not a console power as its not described along with the +32 to Warp Core Potential and Eject Warp Plasma, it looks to me its the Runabout special Ability just like the Ody comes with that Advanced Slipstream ability.
However the console can be put on another small craft.
