has any one else gotten a rare instead of the boxtopper? This kinda suck seeing as how i wanted the boxtopper.....

I havent seen anyone getting a rare instead, but I have seen them just pain missing from the box. It happened to a friend of mine last week when he bought 2 boxes of Tekken and one was missing (and hes just getting back into the game too). It also happened to me way back when Relm of Midnight came out and one of my boxes was missing it's Lord of the Makia.

was it atleast a rare from the set?

Contact the company directly.
