2# achievement is Season Progress and the highest tier is awarded for "Complete all tiers of 100 season achievements". But how we know from announcement there are 300 seasonal achievements. This means we have only 60 FULL achievements - every have 5 tiers.
Of course, at this point we don't know the structure of the next seasonal achievements, but so far all of them (except the hidden ones) have 5 tiers each, which means that there are only 60 seasonal achievements in the game. Is this problem known to the developers and some of the next seasonal achievements will have fewer tiers?
