0Atk Alomomola (Neutral) Waterfall vs 0HP/0Def Sturdy Graveler (Neutral): 95% - 99% (240 - 250 HP). Guaranteed 2HKO.
Not to be that
guy... but, even a Specs Sceptile Leaf Storm is going to have a tough time OHKOing the Sturdy Graveler.
That said, I'm inclined to agree with you.
While Alomomola can be annoying, the most it usually does is manage to Toxic something before getting set up on or destroyed.
