Do people really hate morgana or is that just an inside joke

I don't really get why people hate on morgana. Sure there are times when he's annoying as hell but he's actually a good healer and all...I find him a better healer than makoto. I see people most especially on tiktok saying he's better off benched😭😭 I found morgana really useful especially in okumura's palace and the palaces that come after...in my opinion i think haru is more of a team mate that i benched more, i never used her except in okumura's palace..
