Or instead use Slowking, with 80/80/110 defenses he works well at fending off Moltres as well as many of the threats that Slowbro generally covers.
Also, "Pokemon X having a movepool of X,Y, and/or Z with all possible EV spreads" is a pretty lame argument/ counter-argument.
The option to be versatile and/or the need not to be versatile is an example of a good argument, IMO. Looking at previous discussions...
Yanmega was a very versatile Pokemon having several sets such as LO, Reversal, Specs, and so on at his disposal. However, at the same time he could simply use the Specs Lens set and proceed to decimate teams. Garchomp, Latias (from my understanding), Shaymin, and Staraptor would be another example of a Pokemon in this category.
Cressalia on the other hand had versatility; which I believe brings up the "Pokemon X having a movepool of X,Y, and/or Z with all possible EV spreads" bullcrap. Cressalia didn't have 1 specific set that straight-up owned shit. She did however have access to several support options as well as a means to increase her attack stat. Having the correct support options (in Cress's case, as well as superior a superior stat spread) is all that it takes. Wobbuffet and Gallade would be an example of this class.
And then there are the ones with options but it would be almost insane to drift away from the standard. Honchkrow and Crobat, would be an example of these.
By no means am I implying that Crobat, Honchkrow, or Gallade are 'broken'.
With that said, lets refrain from attacking weak arguments with weak counter-arguments.
