>>29530107Scald is mirrored after Lava Plume 80 BP 30% chance to burn and Discharge 80 BP 30% chance to paralyze. Problem is Scald is given to something that beats Fire and outside of select abilities, Fire is the only thing immune to burn.
Just as Body Slam has variation in BP (85) yet still has 30% chance to paralyze, with a likely higher 85 since Normal doesn't cover anything super effectively, I think the approach should be to change Scald's BP.
Drop it to, say, 55. I think that's fair given the coverage prowess and its being available as a TM. Only stall mons that just want effects like Alomomola or Quagsire would keep them, and then setting up a Sub on them becomes more reliable.
