The number of matches left should decrease more when you get streaks instead of getting prizes.
E.g 5 streak=10 matches

Another thing to get people to farm qi. Not Supported

I don't see why getting streaks would gain you more matches played. That is like saying give me 10 iPads because I have already bought 5.

I think you should rather get 100 tc for a many streak but not extra qi

Yeah, Brice and PVPPRO, both of your suggestions are good in theory but they would increase the amount of farming.

Anf this would totally counteract the implement that hampa/whoever did with the tourneys
if they just got in a room with their alt and got a win streak they could do this over and over and over. making the tourney farming epidemic happen all over again
