>>51685222Don't feel bad, I re-read my post and it very much comes off that way.
It's less that I forget about them; it's more that those are the Pokémon that I can get by the time I can use Fly, that make the best use out of the move.
I definitely wouldn't want to slap the Physical move Fly on the Special-Attacking Noctowl, for example.
Of course there ARE other Fly users, but what ends up happening is that I want to avoid as many dead moveslots as possible. Thus, in for example a Johto game, I'll pick up Pidgey (or nab the Gift Spearow), knowing that Skarmory is obtained a fair bit after the Fly HM is (plus it's a version exclusive), and 80 Base Attack Pidgeot, using 90 Power STAB Fly is pretty good.
Then I'll think to myself "I don't want 2 Normal-Flying Pokémon, that's sorta lame" meaning I'll never use Noctowl.
It's not that I don't know there's other options, it's that I don't want to grind up another Pokémon. I like to plan 6 at the outset and run that combo through to the Champion, saving my patience for EV Training up a Battle Frontier / Battle Tower / Whatever-This-Particular-Game-Calls-It team.
Is this me being lazy? Probably, but it's how I approch playthroughs these days, unless I'm doing a Hardcore Nuzlocke where grinding is a guarantee, my Route 1 bird is bound to kick the bucket at some point and sometimes I'm gonna end up with a Pelipper whether I want one or not.
I guess Gen 3's kinder on that front than I gave it credit for because you have:
>Swellow which I already mentioned>Pelipper which sucks Physically but the choice is there>Crobat which is in every damn game>Flygon can learn it according to Serebii; how have I never noticed this?>Skarmory>Altaria>Tropius>Salamence if one is willing to grind in a Pokémon game's main storyline.
