I think Regigigas should have a higher rating for Rock Smash + Heavy Slam than Rock Smash + Stone Edge.
While Stone Edge deals higher DPS, Heavy slam has higher DPE and DPExDPS, so to say it’s Regigigas’s “weakest charge move” is actually wrong depending on how you look at it.
Also, the article goes on to say that RS + SE deals synergy against Ice. While this may be true, Steel-type Heavy Slam also has this same synergy against Ice. I did some research on the DPS TDO Comprehensive Spreadsheet to compare the performances, and with the current moves available against Regice, Regigigas actually dealt 1.109 DPS points higher with RS + HS than RS + SE. Not to mention that beyond Ice, RS + HS also has synergy against Rock, too, giving it even more reason top be ranked higher. RS + HS has synergy against 2 types, being Rock and Ice; RS + SE has synergy against Ice. Clearly, a more flexible move in terms of type coverage.
Is there something that I’m missing? What do you guys think?
