Morgana just looks terrible IMO, if she does get the victorious skin, which it looks like she will, she should definitely get a VU or else it will just look horrible, unless riot pulls an udyr and keeps the bad classic skin and just makes one single skin steal the spotlight like they did with spirit guard.
I personally was really disappointed to see that Morgana would get a victorious skin, she's a boring looking champ and her spell animations look boring as well, not that there is much to a spell shield, a small puddle of goo, the binding and chains from her ult are the only 2 spells that slightly stand out and I just don't see how riot could make those look at all interesting without a VU. Come on riot, it's not too late to change your mind and give a different champ the victorious skin, i'm sure there would be more happy people this way.
