I am playing the Gears of Dreadlands Demon Hunter build.
With the additional movement speed from the Altar, the additional movement speed from Smoke Screen/Displacement (+100%), the additional movement speed from a Speed Pylon, and the additional movement speed from the set itself, I am moving at sometimes +475% movement speed, and it is possible to outrun the mechanism that auto picks up Greater Rift Progress Orbs.
I noticed that after dropping, there is a delay of about one second before these things are picked up, and if the character is sufficiently far away, one or more will be left.
For this particular build, it tends to defeat the purpose of the ability, because regardless of what gets picked up, I find myself circling back to see if any were left.
