Alright, I'm just gonna pop in and say that the Mega slot argument is pretty damned ridiculous. If you're using a specific mega, you're using it for the specific strengths it provides for your team. I'll use Mega Manectric as an example since that's the topic right now. There is no opportunity cost in using Mega Manectric as a pivot in your mega slot because no other mega does the job better. Sure, Charizard, Pinsir, or Venusaur are generally better than Mega Man, but not as pivots. You don't just slap a mega on your team because it's a mega, you put it there because of the things it does for your team.
Also, I support Mega Manectric's move to A-. I honestly cannot see where demotion arguments are coming from. What you guys don't seem to understand is the difference between offensive and defensive pivots. Mega Manectric is the former. Blistering Speed, great Special Attack and coverage, and Intimidate make Mega Manectric excellent at applying offensive pressure to a team and it's very easy to take advantage of with Volt Switch. If you play it correctly, it won't have to take hits. It seems really clear that  people arguing for a drop either haven't used Mega Man or don't know how to use him correctly.
