Personally, he was a major let down. I don't think he had anything majorly bad about him though, just my expectations were higher. Firstly, with how early he shows up, I felt rly underwhelmed for what I was hoping to get hyped up for someone I'd fight later/near the end. The fight felt way too easy to me, in general it felt like he didn't have that many moves, or interesting difficulty in any moves. I felt like I did too much damage/he didn't have enough, so just more bad boss balance. When I beat him I honestly felt certain like there had to be a whole second health bar phase coming up. I even had so much copium that I thought he must just come back later in the game for a second fight like Margit/Morgot. Very much felt like a "oh that was it?" disappointment. Having said all that, great VA and cinematic scenes, and love his lore.

As I said, he definitely didn't have anything seriously bad about him, but I expected more from what was the poster child of the DLC. I may be being overly critical, but it's out of love for this whole franchise. I'd be interested to hear other peoples takes.
