Life Remnants/Sanguimancy - Collection range mechanics

I've heard tons of complaints about Life Remnants, but I like the mechanic. I heard one suggestion though that I think should be implemented: Increased collection range for the life remnant orbs.

Here's an interesting way to do this:
1) The orbs move slowly towards the player.
2) Life Remnants can be buffed by duration support gems, increasing the lifetime of the orbs, effectively increasing the collection range.
3) Life Remnant can be buffed by projectile speed support gems or a not-yet-implemented movement speed support gem (could also affect minion skills). Makes the orbs move faster, effectively increasing the collection range.

This mechanic will make the blood mage more fun to play.
