HI !
Its not a realy “BUG” ! its more then like a “Mistake” !
I noticed that zagara in mastery page have two wrong link !
in Power set 2 , Mastery 1 (Intensified frenzy) is linked to Power set 3 , Mastery 1 (roach damage and life)
and in Power set 2 , Mastery 2 (zergling evasion) is linked to Power set 3 , Mastery 2 (baneling attack damage)
In fact we can give TWO “30 / 30” in ONE Power set !
the true connection is every mastery linked to another mastery in SAME Power set! not another Power set !
(Power set 1 is Correct)
I hope I helped !!!
