The league of assassins meta is only fun for assassins at the expense of all other roles.
It's literally not fun just to watch the overly mobile assassin insta-killing whoever the fuck they want as the players that didn't choose an assassin pray the enemy assassin is horrible or their assassin is better than the enemy assassin so that they get their participation win.
I DON'T FUCKING LIKE TO PLAY ASSASSINS, I DON'T WANT TO PLAY ASSASSINS, ASSASSINS AREN'T FUN TO PLAY AGAINST ESPECIALLY WHEN THEY'RE THIS GOD DAMN OVERPOWERED.
They literally don't even have any trade-offs for their mobility or damage. They're not outplaying other people, they're just taking a champion that has the tools to kill their prey while the prey is just that, prey, because Riot's neutered everyone but overly mobile assassins so much that they're literally just feeding off of anyone that doesn't play someone with 17 trillion dashes. It's stupid. Tone down the damage, tone down the mobility, and actually give these idiot assassin players something to think about and have to semi-strategize about instead of gifting them with everything while neutering everyone else so we're just lambs to the slaughter to these overly mobile idiots.
