Whoa, whoa, whoa. You can't just take Cofagrigus out of the top 10 like that. The metagame may be more offensive but that's why more people should use offensive Cofagrigus which is actually good, especially vs. offensive teams.
Number one should be Kabutops. It's certainly the most used pokemon on my team. Practically every pokemon that needs a spinner has better offensive and defensive synergy with Kabutops than any other spinner. He's also the best at what he does. He spins and sets up Stealth Rock while still keeping the team offensive and not being set up fodder. He's got priority and still checks a decent amount of pokes, what with all the fire power in the metagame. So he's obviously not the most dangerous poke in the metagame, but I think he's the most help to any team.
