>the few usable Rock types would suffer for not being able to hit them super effectively with STAByou mean stuff like diancie, tyranitar, aerodactyl, tyrantrum, rhyperior?
without rock weakness (including the stealth rock damage, only 12,5% taken):
>208 Atk Mega Diancie Diamond Storm vs. 32 HP / 0 Def Regice: 186-220 (60.1 - 71.1%) -- guaranteed 2HKO after Stealth Rock>+1 252 Atk Mega Tyranitar Stone Edge vs. 32 HP / 0 Def Regice: 291-343 (94.1 - 111%) -- guaranteed OHKO after Stealth Rock>+1 248+ Atk Mega Aerodactyl Stone Edge vs. 32 HP / 0 Def Regice: 276-325 (89.3 - 105.1%) -- guaranteed OHKO after Stealth Rock>252+ Atk Tyrantrum Head Smash vs. 32 HP / 0 Def Regice: 256-303 (82.8 - 98%) -- 68.8% chance to OHKO after Stealth Rock>252+ Atk Choice Band Rhyperior Stone Edge vs. 32 HP / 0 Def Regice: 285-336 (92.2 - 108.7%) -- guaranteed OHKO after Stealth Rockall common sets. used regice as a generic ice mon (tho it has higher base defense than the average ice mon). avalugg obviously survives, but i think that's nice for a PU mon that can't do much to fight back anyway. admittedly, diancie can't do the ko. but i think that's fine for an A+ rank mon. plus regice is stuck with a 2hko too with focus blast, and since diancie is faster, it loses.
as you see, the good rock types are fine, provided they have boosting moves or a good boosting item. ddance tyranitar is common, so is hone claws m-aero.
now for the shittier rock types (barbaracle doesn't count since it usually has cross chop):
>252 Atk Archeops Head Smash vs. 32 HP / 0 Def Regice: 259-306 (83.8 - 99%) -- 75% chance to OHKO after Stealth Rock>+2 252+ Atk Life Orb Carracosta Stone Edge vs. 32 HP / 0 Def Regice: 409-484 (132.3 - 156.6%) -- guaranteed OHKOthe only things that miss out are cradily and aurorus, which are support mons, and regirock, which admittedly isn't ideal, but it is mostly used as a support mon too anyway.
