Metagame is done, i expected gen 6 to fix the retarded metagame from gen 5, but it only got worse, it when from broken dragons, broken weather, broken entry hazzards to keep them and add broken megas, broken items and broken abilities.
In order to be somewhat competitive... out of the 18 types you must use a steel type in your team, out of all the pokemons you must use a pokemon with a mega evolution, out of all the pokemons you must use a pokemon with stealth rock, out of all the pokemons you must use one with knock off, switcheroo, defog, rapid spin...
All this cherry picking makes usage tiers to become smaller and smaller, and the sad thing is, good pokemons aren't being used anymore, not ok pokemons, good pokemons.
