Stop running shitty stall, thats your answer for gothitelle.
Gothitelle alrd in PRO for long long time ago but no one care to use it, you know why? because its not that good pokes to begin with in PRO.
Gothit start to shine when regenerator introduced which makes pokemon like slowbro overpowered and abused by many ladder climber, and Gothit can shut it down completely along with another STALL pokes. In result those stall players get salty, that this threat all about.
Check ladder some poeple even manage to get high win:lose ratio without using that overpowered gothit you mentioned, and if gothit that OP they will never get such win ratio right?
