>>29557728Gen 4. It introduced the physical/special split, moves, and abilities to help out pokemon and give them better STAB and coverage options. Overall the most balanced metagame.
All the gens below 4 lacked the physical/special split, so lots of mons like breloom couldn't even use their stab attacks reliably and had to rely on strange movesets with hidden power for coverage. lack of items like choice scarf and choice specs also cucked some other mons.
Gen 5 was a cancer fest with infinite weather bullshit. Sand Veil and Sand Rush were broken as fuck.
Gen 6 fucked over the balance of the metagame as well. Fairy mons have an unnecessary amount of resistances, take care of types that are filled with offensive mons, and are only weak to Steel and Poison types, which have an abudance of either defensive mons or shitmons that lack the proper attacking stats to reliably take care of fairy types. Megas were a hit and miss. Some of them didn't even improve a pokemon that much, but others like Mega Kangaskhan were broken as fuck and unnnecessary.
