I really think that you are underestimating Alomomola. Mola isn't supposed to be walling every physical attacker in existance, but rather being the best initial response to every one of them. Take NU as an example, while mola cannot directly counter CB Sawk since it is 2HKOed by Close Combat, it can scout for its move and switch into something like Haunter when confirming it is locked into CC, recovering sufficient health to take hits afterwards thanks to Regenerator. This is pratically the same case in RU as mola can take a hit and switch into corresponding check when facing a physical threat. This alone makes mola a precious pivot for offensive teams since offense cannot afford to have counters for every single threat in the tier. Having Wish + Regenerator is also one of the key factors for mola to be successful since it can recover both its own health and its partners health in one turn, making it the single best wishpasser in RU. According to your calcs, many things like CB Druddigon and CB Braviary can barely 2HKO mola with a small chance which isn't even including protect. I don't really get why you think mola will be killed since from then on, mola can simply wish+protect to stall or wishpass when the opposite side switches. Mola's sheer bulk and utility of wish gives it a position in both offensive and defensive teams and therefore should be fitted in Low S.
