What happened to Slaking's stat?

It should be since only charge attacks do damage. Don't be fooled, Mewtwo is still way better.

No change, it has always been higher than Mewtwo. Thing is, not dealing damage with the fast move is a very big deal.

It always is but Slaking is worse than Regice or Giratina on offense. You read it right. Not using a fast move has this difference.

P.S. i tried giving Slaking scratch in the gp spreadsheet and it had around the same dps as rampardos with much higher bulk.
