I'm sad that I have to do this cause I used to be this things greatest proponent, but I think Manectric needs to be moved down to B or C tier. The metagame is no longer as weak to Electric as it once was, meaning that Manectric's STAB is much less easily spammable. Te drop of Nidoqueen means that Manectric can quickly become a liability by giving that free turns. But the biggest detractor is Lanturn. With the threat of Moltres, Lanturn has become very common, and Manectric is completely shut down by Lanturn, entirely useless against teams with it involved.
Its been an unfortunate fall from grace but Manectric is no longer good in RU.
