Mordekaiser Ulti Bug

So today...during an ARAM, i (morde) ultied a Garen. Nothing special, he took damage, he died, he became a ghost, and was an FOREVER SPIN TO WIN GHOST. it was freaking awesome.

Garen was at extreme low hp, when i ultied him, it was an instakill from the damage. he was SPINNING at the time i killed him, and the ghost spawned forever spinning. all visual effects and was a beautiful thing of masterpiece-ful awesomeness. when the 'spinning ghost' got into melee range of anything he stopped spinning as began to do standard AAs. upon moving again... the whirlwing of awesomeness continues. (the spin did no damage, purely visual)

please keep this bug in the game. PLEASE RITO.
