Teleport Nerf was uncalled for. And pointless
Once upon a time Riot looked at LCS and saw that teleport was picked also by midlaners and botlaners.
Since we must have variety in summoner spells that aren't flash, riot nerfed tp.
Joke's on them: the problem never was that tp was op in the first place! Everyone ditched heal and barrier because in such a ridiculously high damage meta they were utterly useless! Currently, if anything is going to happen in competitive, it is by number advantage, and chances are you're going to die regardless of extra hp or shields! Apparently Riot, despite having almost a decade of experience in balancing the game, didn't see that and instead concluded that nerfing to would have brought more variety to competitive.
Results of that change: everybody in proplay still picks a nerfed tp, and nobody in soloq picks tp (they all run ignite).
Clap clap
