This question has riddled me for as long as bonemerang's existed.
Every set I see always lists these over those
Earthquake over Bonemerang
Dragon Claw over Dual Chop
Moves with the same base power (100 for earthquake, and 2 50s for Bonemerang, 80 for Dragon Claw, and 2 40s for Dual Chop).
Now why is one better than the other? the 90% Accuracy is the only bad point I see, but that doesn't stop people from using Heat Wave over Fire Blast.
now figuring in STAB, doesn't Bonemerang do more damage than Earthquake, in addition to breaking Subs? (or they might be similar due to Earthquake's STAB). And Bonemerang has the joy of not hitting your partner in Doubles.
It seems the Benifits outweigh the disadvantages.
So my question to you all is
Multi-Hit or 1 Shot?
