[GAMEPLAY] Mordekaiser's Ghost Dragon has only around half of it's maximum health.

This has been around for a long time, ever since I really started to play Mordekaiser (started in S6). This isn't intentional as it isn't listed in any patch notes nor on the tooltip. Whenever Mordekaiser slays a dragon while his ultimate is up, the dragon has half of it's intended max health (more or less).

Example: Let's say the dragon's max health is 5500. If Mordekaiser slays the dragon, the ghost dragon's health is close to 2750.

How to reproduce:

Step 1. Kill Dragon as Mordekaiser while having at least 1 point in Children of the Grave Step 2. Look at Ghost Dragon's max health

This happens 100% of the time.

Video proof (dont have recording software so I just stole some videos):

https://youtu.be/zX37fa2c37k?t=3m8s Dragon's Max Health is 5900. After Mordekaiser kills it with his team, the Ghost Dragon is seen to have 2609 Max Health. https://youtu.be/NKizimO4Q78?t=25m20s Dragon's Max Health is 6860. After Mordekaiser kills it along with a Yasuo ghost, the Ghost Dragon only has 4106 Max Health.https://youtu.be/MvjXSfdSxsA?t=5m45s Dragon's Max Health is 6140 (hard to see with the video). After Mordekaiser kills it with his team, the Ghost Dragon only has 3382.

This bug is huge if you think about it. It's like if Alistar's ult only gave 25% damage reduction or if Gangplank's ult only shot down 6 waves.
