Kassadin
The mechanic
Kassadin is deliberately weak early and becomes one of the strongest champions in the game once he has levels and items. His team has to survive rather than fight.
Why it needs saying
That gap causes two misunderstandings: allies count on him too early, then vote to surrender right before he matters. Two lines prevent both.

what you type
im weak early just farm
in full english
I'm weak early, I'm just going to farm.
the context
"Early" alone reads as "early game". Saying it stops your team expecting you in fights you cannot hold, and heads off the blame.

what you type
dont ff im strong late
in full english
Don't surrender, I get strong in the late game.
the context
Probably the most valuable line on this champion. A team that surrenders at fifteen with a Kassadin throws away a winnable game.

kass scaling end it fast
in full english
Kassadin scales, we need to end the game fast.
the context
"Scale" is a verb in its own right here: he gets stronger with time. Against Kassadin the clock is the enemy.
