>>57962655>was an absolute dogshit decision I think you haven't played enough oldgens if that's your honest assessment.
>failed to nerf those it was supposed to balance out (Mewtwo and Alakazam)First, from my understanding of Gen 2 Ubers, Mewtwo isn't even the top dog. Tyranitar exists which makes the lives of many Psychic types difficult because of its Rock/Dark typing and STAB Pursuit off 95 SpAtk.
Second, in Gen 2 OU, neither Alakazam (135 SpA) nor Espeon (130 SpA) are tiered as OU nor even often brought. Perhaps they would be better if their SpDef was the same value, but the lack of that is not the primary reason why they are merely demiviable. If it is true that in a sense the split "failed" to nerf them, that would in another way be a good thing because they were already nerfed by the introduction of Dark and Steel, to such a level that you have to actively think and weigh opportunity costs in order to bring them to battles with a chance of success.
>instead nerfed everyone elseThe only mons I can think of which received harsh nerfs on account of the split are Chansey and Hypno. As far as I can think, nobody else was unfairly impacted. Note the keyword there.
>making the problem children even more problematicAgain, that's false, considering the very next gen maintained their middling status created here.
