Realizing how bad learnsets used to be

Decided to play through RSE again using Pokemon I've never used before and MY GOD are some of the learnsets horrible. Seedots line doesn't learn a single grass type move by level up at all, you have to fully rely on TMs that are one time use. Like WTF. Mawile, a pure steel type mind you, learns one steel type move period. Level up, TM/HM, breeding, tutor, ONE steel type move and it's fucking iron defense. What were they smoking when they made these games. I'm sure there's more, sadly, but hopefully they're not this ridiculous
