Alosso,i'm not sure if we are saying the same thing or not,
We are not.
I understand you saying "there are no set requirements for tiering up on the mobile device", I say "There are, and more than one."
In the mobile version,tiering up is not dependent on levels or avgs or ranked rounds(as only tournaments and ranked rounds played alone count as rrds).
Looks like I have explained my opinion many times in this thread. Therefore, please go ahead and explain yours. By which algorithm or magic are players with 150 averages promoted up to Legend?
(easy to find in the players list, selecting the different tiers)
