Also: Space Fleetmarks
If you do the defend the transports one and leave before the timer runs out it doesn't give you a cooldown. So during double marks just leave with 5 seconds left and you still get the marks and can just spam it.
I have both the Tholian Carrier and the Tholian Orb ship. They are PHENOMENAL. Orb is probably the best healer now in game, Oddy and Tholian Carrier are close behind.
Space pvp in STO is epic. Good groups with complementing builds are exponentially better than lolkirk or pugging it. At the highest end of pvp there isn't much variation room, but that's less than 1% of the matches. Everything else there is lots of flexibility to try thing and play with builds. The bad part is cryptic pve development being so fucking stupid that they never consider pvp when putting in new shit. Like leech and lolerons not stacking. Or energy drains not having a stacking penatly. Or theta killing off all your crew till you die and respawn. But the pvp is really good and the mechanics behind them are fairly solid.
