"I'm a ______ Main."
The moment you out yourself as a main of anything OP, you've lost credibility. Take Kat, for example, she's OP, and there's no denying that. The main argument of her mains is timing. But there is nothing about timing that separates a bad Kat from a great Kat. A bad Kat will blink in and kill everything. An amazing Kat will blink in and kill everything. Even if they gave her mana and reworked her passive to refund mana AND CD on kills it would be better. It would take her free harass away in lane, she would have to consider her harass carefully and limit her wandering capabilities from lane (which, side note, it's infuriating that even if you beat her in lane, she'll just roam bot for a double because even if your team listens and back off, she can kill them under tower and get away because of her resets) because she can't just use spells willy nilly. Make her Q a skillshot. It means she can't click on someone for free damage procs. These changes might seem harsh, but a GREAT Kat would still be able to use her, because her damage wasn't touched, but a bad Kat couldn't carry a game regardless of how bad they are. I understand champs are fun and become less fun with nerfs, but think about the game as a whole, how enemies are affected, how other lanes are affected, whether or not the game is enjoyable with you in it.
Edit: pretend this was a post about Lee and his mains.
