If you (Cryptic) want to offer more special services, please think about a race change!
Its (for me) the last wish for a overall new character design... For example... my character is a human and i'am bored of this race. I have become with my digital download version of STO the "Joined Trill" race. this race looks pretty and have awesome race bonusses.
I bought everything in the c-store but the races. If you allowed for is i would not only buy the re-race option, but also a bunch of races. I don't have the time to play all day and level new toons up. If i can redo just the race, this would be awesome, not to mention the class I really wanted (Ferengi) wasn't available when i created my toon.
There are a lot of reasons why people would want to, just set a price and offer it.
I would love to see race changes and Im sure would be a huge C-Store seller.
I would also back profession changes that would also be a huge c-store hit.
There are countless ways you can explain it in RP. Star Trek did with spacial anomalies what comics did with magic and radiation. Picard was turned into a kid wasn't he? the crew was turned into various species weren't they?
RP can explain away nearly every meta change we can do
