Don't know if I phrase the title right.. LOL 
anyways, I think what the Staff should have done instead of the RB thing is like this..
Since like every card seems to have a unique id of sort(cuz card history) they should have done something like a Better stated one out of X amount of copies.
I don't know how to word it so it's like this.
For every X amount of copies of a character one of those would have a better stats like it may have one more power or damage. Ability wise won't be affected just Power and Damage. like out of 1000 copies of Negodz one of those will have a stat of maybe 5/5 or a 6/4(star count won't be affected). It will encourage people to buy more packs. it won't have like a new Title( ex. Cr or RB). I don't know how it will affect the market though..
Cr could have it also making that particular Cr rarer than the it's counterpart...
Since the highest Raw Power available is 9 currently it will be the cap. No raw 10 power cards, sorry. it goes with Damage aswell, cap is 8 I think.. 
I give bad ideas.. sorry.
