New Morde Ability VFX on PBE
I'm not sure what to think of his actual gameplay rework yet (obviously), but I am certain on this - the new VFX are really underwhelming. The Q change is whatever - that spell has pretty much never looked good so I don't particularly care that they've neglected to improve it. The change on W is fine - again, the VFX were never that interesting so I don't much care what they do to it.
The changes on the E are a different story. I always loved having a whole horde of maces pop out of the ground and smack my enemies in the undercarriage. It's satisfying as hell to do and to me is a big part of what makes Morde feel like Morde. Now they've replaced those awesome crotch-seeking mace effects with.... swirls. Seriously Riot - those are just purple swirls that blast out of your face and disappear. How is THAT something you'd measure as an improvement over the awesomely satisfying mace smacks from before?! Really really really disappointed. As far as I know they've done absolutely nothing to the ult VFX which is odd, but w/e.
TLDR - The new spell vfx on Morde are pretty underwhelming. The Q, W changes are fine but don't upgrade the effects in any noticeable way. The change on the E looks awful and unimaginative, not to mention replacing his more characteristic mace effects from before. Booo Riot, booo
