That has got to be the worst thing ever, being so totally over the moon about winning/getting a cool/rare mount and then it hitting you that its on the *wrong* toon. I haven't have that happen myself, unless you can count that it took very much less time for my shelved pally to get the green proto than it took my priest. But it did happen to a friend of mine. We were leveling toons on a server that wasn't our "main" server. We'd started alts there when our server was down, she made another mage, and I made the priest that has become my main. While we were leveling (through dungeon finder), doing lich king heroics, the blue proto dropped and she won the roll. The best part of that night wasn't that she won the roll (well, that was awesome) - but it was the EPIC hissy fit that our tank threw because he didn't win. He cursed his head off all CAPSLOCKY till the end (well till we kicked him for doing more typing than tanking). At the time, she played that mage a lot, though her main mage was on another server. In time though, the main got played more and she was soo mad that her super cool blue proto was not only on another TOON, but on another server. In time tho, I transferred back to the main server and eventually she brought that mage too.. but the blue proto still collects dust.
