The way I see it Chandelure isn't broken, and I don't get why people keep going on about having to run Snorlax, I've never used Snorlax or had a problem with Chandelure on any of my teams. Due to its slow speed even with a scarf it is revenge killed by any other scarfer in the tier. Specs is even easier to revenge kill, since base 80 speed is not very fast for a sweeper.
I don't think Chandelure's presence in the metagame is unhealthy, its like pretty much every other power-house fire type in the tier. They all have access to a very powerful attack (Overheat, V-Create, Flare Blitz) and other good coverage moves.
But in the end I don't care if Chandelure leaves or not. It may be interesting to see if it actually does impact anything, which I doubt it would. And anyway, Chandelure will get banned as soon as Shadow Tag comes out.
