[Gameplay] - Mordekaisers W heal is a slow moving projectile

The heal portion of Moderkaiser W is coded as a non-instantaneous projectile, with no particle effect or indicators. Because of this, if any champion covers large distances of ground while the invisible projectile moves towards them, the heal will be significantly delayed.

Steps to replicate:

1. Be significantly damaged on Mordekaiser
2. Turn on the first part of W near a test dummy.
3. Reactivate W to heal from the test dummy, then flash or teleport away.
4. You can visibly see the large delay on the heal.

This IS gameplay relevant because:

• The tooltip on Mordekaiser's W states: "Reactive to instantly steal health from nearby enemies"
• Mordekaiser might flash away after reactivating W, causing the heal to be delayed and resulting in his death
• An ally with a long range dash might have a significantly delayed heal
• There is no indicator for how long the heal will take to reach him
• The projectile can sometimes be blocked by windwalls/braum shield.
