Mordekaiser Rework 2019 Interactions

I have been loving the new Morde. The revamped ULT is vary flavorable and about makes up for loss of old ULT (miss my Dragon though). There are a few things I am curious about.

Negating Morde ULT with something like Quicksilver Sash is fair. Opponent must invest in item over other possibly more desired ones and has decent cooldown. In contrast, Gangplank orange means never using ULT (unless maybe catching Jungler or other roamer). Is keeping scurvy at bay really a healthy way to escape the forced upon Death Realm? Really would like thoughts on this one as would like to know if this should change or how this makes a healthy game state. Just want to approach my games with the right mentality.

Thresh hooks Morde while casting ULT on another champ. Enter Death Realm and still being pulled along by hook. Unknown if bug, unintended interaction, or just weird interaction. Flavorable though considering Thresh.

Big improvement on skins. Especially like the King of Clubs and Pentakill updates as never felt right hitting with the side of the Axe. Dragon Knight is overall themed instead of just being a Chroma with a Dragon on cape. On the other hand, Lord Mordekaiser seems a bit lackluster. Giant traditional mace, even a bit jeweled is ok, but the loss of the energy ball/aura (moved to Pentakill I guess?) seems to have weakened its impact (PUN wasn't intended, but it works).

So I would like to see what the community, and Riot, thinks of all the special interactions with new Morde, where he stands with current skins, and perhaps even ideas for the next skin.
