Why was Garchomp nerfed so much?

I’ve been playing since the release of pokemon unite and haven’t had any complaints about the game. However, I came back to it a month ago after taking a half year break from the game to find out how much has changed. The new Pokemon are all great, no real complaints, though Garchomp has been ruined by nerfs and unfair disadvantages. He used to be a slow level up, balancing how strong he is, which later was changed to feel less of a waiting game, which barely harmed Garchomp. Though as of recently, he’s horrible to play. The lower crits make him less powerful and the little to no healing makes him pointless against goodra, buzzswole, or trevenant. He can barely handle a simple pikachu by himself as of now. Please, fix Garchomp so he’s usable again, simply giving him back his healing and slightly raising his crit chance would be enough.
