I just got me a Borg cutting beam (I know, late to the party), the only gear so far I picked up from the reputation store. Any other store unlocks worth the investment?
Well the Borg plasma torp gives you a mini V'ger torpedo thing.
And the Romulan hyper plasma torpedo fires volleys that if you skilled right can be heavy plasma torpedoes.
Oh I also checked out the new character selection screen on tribble, now the BO slotted for your way team will show up behind your character and your ship should be visible above them.
