Rune system doesn't solve movement speed in boots

The most important stat in boots is movement speed, and this make nearly impossible someone change boots in campaign eve when hit good stats.
You could make a runes which gives 8%, 15%, 20% movement speed but in someway not add to movement speed of explicits. This change could solve unique boots and make easier change boots.

I double that request for speed runes in boots, but if the speed modifier is could be useful in other gear that's also a plus.

I found so many trifecta boots, but no MS.

Sold as scrap.

Yeah movement speed runes for at least boots really should be a thing
