Why does move speed not give move speed?
Say you have mobility boots and have 473 ms. You buy alacrity enchantment and your ms only goes up to 480 or 483, not to 493. Why is this?

Movement speed has diminishing returns past certain thresholds.

** Movement speed caps** When the raw movement speed is greater than 415, there are two soft caps applied:
The raw speed between 415 and 490 gets multiplied by 80%. The raw speed over 490 gets multiplied by 50%. The two ranges have their reductions applied at the same time before being added back together.
As an example, if the calculated raw speed is 600 before soft caps kick in, it is reduced to (600 − 490) × 0.5 + (490 − 415) × 0.8 + 415 = 530, which means an 11.7% reduction of the original movement speed.
There's a soft cap on movement speed I think at 475 or 480 so you get far less for building MS after that.
One day Riot will realize they can try to design a champion that gains MS per level, and the mobility meta will be busted wide open
Basically what the posts above me said. The reason for this is to prevent champions running around the map with crazy numbers like 550 MS and being practically unkitable.
