Fucking Smogon
"Lets ban Aegislash!"
"Lets ban Gengarite from Ubers!"
Logic: Aegislash. Uncompetitive. Shapes meta too much. Can beat all its counters with the right moveset. Gengar. Uncompetitive. Limits teambuilding.

Yet in Gen 5, Smogon's analysis of Hydreigon (at least on their old page) said that Hydreigon had no true counters. Did they bitch about it and try banning it? No.
"Aegislash can beat its counters with the right moveset". No because half the metagame totally can't do that as well. Talonflame gets past shit like Rotom and Heatran via Nature Power. "That still leaves it countered by something else". Aegislash runs one set, he gets countered by something else. Simple as hell. While we're on the topic of over-centralising the meta, lets go ban Talonflame as well. I mean it's one of the main reasons people run Rotom, T-tar or Heatran. And how about lets get rid of Mega-Pinsir too. God knows how every team needs  good counter to that.
Why don't we get rid of Kyogre in Ubers too. Every damn half decent Ubers team has a kyogre counter. So its obviously limiting teambuilding. Lets ban its ass.
