Does Vayne scale?
Somewhat. Vayne holds up late with the right conditions.
B tier. In theory, percentage-HP true damage is elite. In practice, she is outranged by every ADC in S and A tier, gets poked out before she can close the gap, and has no reliable escape when team fights spread out. Range is the single biggest scaling factor for ADCs.
The grade measures one thing: how much a champion can influence a coordinated late-game objective fight once both teams reach full builds. It does not measure early strength, snowballing, or win rate. A weak late-game champion still wins by ending the game first, which is what the rest of the library teaches.
