Ideally could be a simple web page, you log in with username and password. The page then grabs the info from the AH servers as to what perks you have where. Puts a page up showing what perks you have and offering options.
To convert GV perks to Fighter, make it a hefty 33% service charge. Same for any simple change, fighter to bomber, or GV, GV to bomber or fighter, etc.
To send perk points to another players acct, squadmate etc, should be a fairly minor fee. 10% off the top.
You send "mysquadie" 250 fighter perks so he can up a 262 mission, he'd see 225 arrive.
To move perks from one arena to another, well might not want to encourage that. So make it a stiff 50% fee to do it.
Come on HTC, we have "perks" but you don't let us spend them. We can't convert them, give them away, change them from place to place. Its like worthless money.
Plus once you have a perk point bank, you could have duels that actually have something riding on the outcome.
Imagine Skyrock dueling Shawk for 10k perks.
Either that or make AH merchandise that we can buy with perk points.
20k fighter perks for a hat or something.
