$25 to transfer to another server, $25 to switch character genders?
Yeah, i call that greed.
Greed? I don't really think so. They could charge $5 to do anything, or even just let you do it for free. But they don't in order to bypass the headache of people switching servers, genders, etc on a regular basis. I think they put the prices at those points because for one, they're not unreasonable. You already pay $15 a month to play. A few dollars extra shouldn't hurt anyone's wallet. For two, it's not an amount you're going to just scrounge out of your couch either. It's a deterrent to incessant switching.
