I would prefer no new currency introduced. What I would like to see is something like the Commendation Tiers for Duty Officers. As you participate and win matches, you gain PVP Commendation XP, and once you reach a certain level, you gain access to items in the PvP Store. Some stuff is for free (Say, Titles). Other stuff costs Energy Credits, Dilithium or Latinum.
The store could contain DOFFs, BOFF Trainers, Gear (including new Sets).
PvP only area, like Drozanna that is neutral, perfect.
It is a place to hang out and share your funny fed busting pvp tall tails and maybe buy some cool pvp related item: such as badges for clothes, or actual clothes, more damage choices at tailors, trophies, oh please trophies and symbols/decal for your ship. I want phaser burn damage and the no. of fed ships I have destroyed, or is that just me ?
Not pvp boosting rewards like consoles etc, which was discussed in an earlier post, giving a very good argument against that type of reward.
Love leader boards, where you could be given rewards/buffs, off titles and accolades. Some permanent, others like doff buffs, lasting an hour. Commodities and dilithium would be great incentives and rewards.
