>Pokémon games are too easy, they need to be more challenging
>Infinite use TMs are a good thing and old games suck because of limited movepools

You can only pick one. Having to make do with weaker moves like Spark, Aurora Beam and Psybeam instead of Thunderbolt, Ice Beam and Psychic is a valid way to make the game more difficult. And so is forcing you to make tough decisions about which of your team members will make the most of the better TMs and which ones will have to do without. Only retards complain about the games being easy while simultaneously wanting to be able to slap Earthquake and BoltBeam on everything with no repercussions.
