Can we Cap MS?
Just played a game where the opposing ADC had a draven + yummi. Now I don't claim to be a perfect player but the draven I feltappeared to be walking right outside of my spells when they were directly casted on him. TBH it felt like the draven had
active 24/7. I was playing

Any insight as to how MS can be capped? perhaps make it a unique passive? the stacking of MS after MS made him impossible to kill. We were able to get him a few times due to lucky spells, slows hitting him etc but still lost the game.
Edit: Would like to clarify as some players are attempting to conflate this argument with player skill. The argument is solely based on the fact that MS has a high presence in the current league meta. Too much of one thing in the game upsets the balance, reducing the effectiveness or omitting certain champs. If said champion has a MS of 500-600 the margin of error increases significantly for a skill shot player. I'm not asking that MS be capped severly or removed from the game but riot does need to introduce a cap to provide a healthy balance.
to send ghosts after them,
any of these 2 with or without glacial and they'll never move again.
