Elite Streak Badge

I believe I saw one with 2 teeth at mere 5 wins.

The 4 teeth is at 20 ( I haven't seen less)

Sadly I haven't noticed mine change at all while I was doing it, so can't be more concrete.

I broke my streak at 28 and it was still the same as 20. I really don't have the patience to give it another try, since my BP is finished.

I would be sad panda if the next one is 30, but I would guess it's at least 50.

Also, I don't think there are so many "stages":

1: basic

5: 2 teeth

20: 4 teeth

50?: +flames? (haven't seen that one yet)

If 4 teeth is actually 15, then maybe it could be 5-15-30.

Anyway, I haven't played after last patch yet, but if 1st zone really does 15%/tick now, there's no reason to even bother with elite anymore. You'll get unreachable zone within 10 games.
