In that case, wouldn't it mean that Robbie and Rory McAllister, as well as Jinder Mahal are all deserving of the Unique gimmick as well ?
The Highlanders are Canadian just like Piper, meaning they can't use the Braveheart gimmick, and Mahal is currently using an Arabian gimmick down in FCW but is also Canadian meaning he doesn't fit the gimmick either.
Also Shawn and Arya Diavari should be placed as American's and given the Unique gimmick to, because they also play Arabians.
Not trying to argue with you Shakespeare, but you brought up a good point I just wanted to elaborate on.
My bad. I should've clarified on point two, it should be used as a last resort if nothing else fits. There are other gimmicks besides Braveheart that could be used for the McAllisters, even though that one is ideal. Weirdo comes to mind, or fun babyface.
All in all, I just think on average, the Unique gimmick should be reserved for very special cases.
One other thing I forgot to say: in the game, the only way for someone to obtain the Unique gimmick (without it being assigned at the beginning of the scenario) is for them to be involved in a segment that gets a 100% rating. That's something I think Piper has done several times in his career, but something the McAllisters probably haven't. Just food for thought.
Actually on a side note, both the Highlanders are Scottish, they moved to Canada in the late 80's.

This is the article I remember reading when they were signed. So if they're in the game as Canadian, it's wrong anyway. (I haven't checked, admittedly.)
