[GAMEPLAY] - Mordekaiser R ghost bug

Good day Sirs ! I'm having this trouble for a long long time with mordekaiser and decided to post it because it just doesn't feel right.

I played enough Mordekaiser to see that his ulti, the ghost , doesn't act properly. When you order your ghost around it doesn't respect the orders, it runs around on its own. When you put it to atack a target sometimes it does that but most of the time it just switches target, in drake case it switches before finishing animation atack. And no im not out of range. Also when i order it to atack someone and i r. click on another enemy champ the ghost starts to act wierd and gets stuck between following me and atacking my main target and atacking its ordered main target.

I believe that when you order your ghost around it should be only with R , no alt+r. click or r click because that may cause some kind of confussion and it makes the ghost switching over target or walking. Also when you order your ghost to atack a champion or a target with R it should stick to it and do only that till morde gets out of range. I think that feels more right.

I played like this many many games and after the last game where the drake acted all strange i thought thats about it. It was clearly a bug, i even have the record. Try it with the ghost in a teamfight. It just wont follow (70% of the time) its main target :( . And i'm getting frustrated :|
