I said damage wise you can compare Magmortar and Combusken, because as you said the most common set is special for Combusken and Magmortar gets about the same moves and hits harder therefor outclassing it. There's also a lot more i said to the argument such as IF Combusken misses its low accuracy moves that it is basically a wasted mon, Rotom frost on the other hand doesnt automatically lose if it misses a blizzard, because it has decent bulk. Orciorio and Swanna both run fly z for the fact that hurricane just isnt accurate or reliable, for those who run scarf Oricorio they know the risk, considering hurricane helps Oricorio a lot more than focus blast helps Combusken in this current meta. Its not a hate missing thing, its more of a you will always miss when you need to land type of thing. To me it really doesnt matter if Combusken runs physical or special, there are plenty of counters in the tier for each of the sets and based on who your opponet sends in Combusken against, its not too hard to figure what set it might be. (You have Regirock, opponet sends in Combusken, its probably a special Combusken).
