that's a lie you know it
nah I loving hate damage creep and mobility creep. Most teamfights last ~1-3 seconds in my soloq games and the engaging team usually wins because everyone gets caught out by a Malphite ult or something and 100-0 . Like I understand that high elo teamfights are shorter than low elo teamfights are, but how the forget is anyone supposed to to react to such ridiculous burst? Literally everything does too much damage
Mobility creep is also cancerous, and the only way to address it is either longer cooldown (which nobody wants) or adding the "Grounded" debuff Cass has to other spells, which nobody wants either. The game just isn't fun when a fizz can jump over a wall, 100-0 anyone on your team, and then just hop back over and avoid retaliation with his invincibility frames.
And black cleaver is broken, I don't know a single champion that builds black cleaver as core that's in a bad spot.
