This is the Ultimate change from Riot August. For Morgana, it is difficult enough to stand close to enemies because you are building as a squishy with ardent censer like items.
Soul Shackles allow Morgana to move faster to enemies. At RANK 1, we get how much? 5%.............. I have used Approach Velocity, and I'm sure it is much faster than the R of 5% at rank 1.
It will eventually increase to 55%, at lvl 16, but how is this even useful when you will get bursted instantly?
BASICALLY, Soul Shackles received nothing from the supposed "rework". A danm shame to Morgana mains.
