Their account system is rather bugged. My main account was created about 2 weeks before F2P, I've applied Rift Deluxe and SL codes -> I had patron status 2 weeks into F2P.
Well, the patron ability tab is gone, but am still getting the mount speed bonus. Which is rather annoying atm, cause my warrior is leading my clerics, and running away from them all the time. Will have to use one of my clerics as leader when moving around.
