If an attack damages >3x total HP, that pokemon should straight up die pemanently.

Stat moves should generally be buffed. 2 turns to halve opponent defense is fucking useless when you usually KO/get KO'd within 3 hits anyways.

Most pokemon should have Nidoran-style gender differences. GF should focus on adding this for the entire dex instead of new pokemon.

Remove type weaknesses that doesn't make any fucking sense, like Bug on Dark. Also Flying type should resist electicity, not be weak to it you dumb chinks.

Single type pokemon should have 1.66 same type attack bonus instead of 1.5

Remove fairy type

Minmaxxed mons like Shuckle should have unique moves that make them viable

Unevolved mons should generally have slightly higher speed stat than their evolved form at same level

Pokemon should get better at using moves over time. Moves start at 100% when learned and get like 0.2% boost per level up. This makes earlier moves more viable to keep around. Also adds another layer to training

Pokemon babied with poke centers and potions all the time should get sligthly less (Sp)Def EVs

All bug pokemon should be shit until they reach stage 3 and get a second type.
