Antimatter Spread should be a Bridge Officer power in my opinion. It could be another Engineering ability, more specifically a "tanking" ability used to draw "aggro". (Even in PvP, where this normally isn't possible.)
Antimatter Spread (Ensign Engineering Bridge Officer Power)
Recharge: 60 seconds
Global Cooldown: 30 seconds
System Cooldown: 15 seconds, Weapon Modification*
Effect: For a duration of 10 seconds, the ship emits antimatter particles. Any hostile ship within 3 km takes [DAMAGE TBD] per second and has a 10 % chance to change its current target to the attacker.
*) That's the same system cooldown as the Directed Energy Modulation power has.
I was wondering if anyone else would use this skill for their bridge officer? Because I would...
