Redirect XP from challenges to chosen class?

[Saccharin]

Well, yes we can do it manually. That involves stopping whatever you are doing, switching to the class you want to give the xp, warping to a suitable zone, wait for cooldowns, complete whatever the challenge is for, then warp back after switching your class back to whatever it was previously. That is assuming it isn't a challenge involving dungeons. o o;

Maybe they want you to play the class that you want to level. Crazy, I know, right.
