Make movement speed implicit

I think everyone would agree that movement speed is basically a requirement at high level.

My proposal is for GGG to make movement speed a implicit tied to boots item level. Kind of like how belts can roll between 1 and 3 charm slots.
Increasing the level would also increase the range of movement speed that could be rolled.

examples of my idea (not perfect or thought out)
Boots at item level 10-20ish could roll 0 to 10% movement
boots at item level 20-40 could roll 10 to 25%
40-70 10 to 30
Boots at item level 82 could roll between 10% to 35%
