what an optimist you are. it will be 2500 zen only if it is not account wide unlock
As you may have noticed lately, Cryptic/PW seems intent on overcharging for their items, and making them CHARACTER specific. If the same people are in charge of deciding the cost for the Regent Class, that set the price for the "Combat EV Suit", then it WILL be a character unlock.
I would much rather pay for the SKIN for like 500 Zen, and keep the standard Assault Cruiser BOff layout. Remember when they used to sell just the skins for ships? Last new skin that was added (and subsequently removed), was pre-F2P.
