Seriously if you guys let me vote then UU would be so much better, we could be freed from the evils of broken things like Chandelure and Hail.
But not today I suppose, not today so instead I'm hoping that somehow my post will influence you voters.
Mew should be banned because it is too strong of an offensive threat. That threat comes from not only it's moderate initial power but more so the fact it can run a variety of sets both physical and special. Counters to one physical set, Sableye for instance, are completely destroyed by special sets. Mew is so powerful that it cannot even be reliably checked as Baton Pass sets can almost always get a pass with Rock Polish and then something else. Even if you know Mew's set, the most dangerous sets which are Nasty Plot and Swords Dance can completely destroy defensive and offensive teams respectively because of power, speed and coverage. Kingdra also has enough bulk to consistently set up and even use a stall breaker set which renders almost all of his defensive counters useless, putting unfair pressure on stall teams. That's why Mew is broken.
