Sadly it's a bug a Cm on reddit confirmed it already.

Confirmed in Standard.

To top-notch players this is not important, for the try harders that reach legend grinding thru many hours of playing, this just removed a part of the grinding.

It is been a long time since the last time I reached legend (march 2016, if I remember right) cause I don't have much time lately. So I enjoy the change, reaching rank 5 with few playtime may be easier now :)

Most probably it WON'T

BBrode: It was NOT intended

Ok so it did do the winstreak bonus after 2 wins up to level 10.  Once at level 10 it stops.  I haven't gotten on a 3 win streak at level 10 yet so not sure it if reverts to old 3 wins in a row until level 5 or each win is only one star.  If that IS the case and each win only gives one star at level 10 it'll actually make it MUCH harder to hit legend.  Quicker to 10 but slower to legend.

Ok just confirmed got a 3 win streak and got the bonus star again.  So now it's like this:

Higher than level 10 gives extra star at 2 wins in a row.  At level 10 you need the old 3 win streak to get to level 5.  I'm guessing it's the same at that point where each game counts at level 5+.
