Posting here to get the opinion of other QC members. I think we can all agree that Crobat is one of the most important Pokemon in the metagame right now, and as such, I would like to get answers on this quickly.
The on-site spread for Crobat is currently 252 HP / 116 Atk / 4 SpD / 136 Spe, however, this spread fails to OHKO 0/0 Scrafty even after Stealth Rock damage. This is not good, considering Scrafty could just Dragon Dance on the switch, then do so again as it tanks a Brave Bird, and proceed to OHKO Crobat with +2 Ice Punch / Zen Headbutt.
I'm proposing we make the primary spread 176 HP / 192 Atk / 4 SpD / 136 Spe. This spread guarantees the OHKO on 0/0 Scrafty after Stealth Rock damage while still hitting the same Speed benchmark (max base 115s).
