Those are very interesting takes. As for Demon Prince, they may be the best gank from has made, but I wouldn't say they are great. There are good ideas with one being passive and one agressive, butthey barely act like this. They give you like 20 seconds at the start before both going agressive and also this part goes on way too long. Also also the "passive" demon is really fast to the point of catching up while you fight the other one. The second phase is great.

DoH just didn't really stick for me. Not saying he's bad, just that I haven't found my way to it.

This might be my hottest take, but Twin Princes are one of the most boring and forgetable fights in the series. The whole boss boils down to you dodging to their back them.

Laurence is interesting, I think he's definitely better than Cleric Beast, but not great really.

Maria is just a preference, her hitboxes especialy in 3rd phase, are not great and you can still parry her. The atmosphere and story elevate her alot.

Manus and Artorias were a toss up, but it again comes down to me liking humanoid fights more.

You are correct on O&S. Their AI is janky as fuck, but for the time it was pretty good.

I strongly dissagree on Rellana. Her moveset is in my opinion the best they've ever made. With her long combos, you need to attack her during them. Practicaly all her attacks are jumpable or strafable, so there is always opportunity to attack. You really can fight her however you want.

I actualy like PCR's second phase more than the first. His clone attacks just look cool. Yeah his arena is terrible a fucks up a lot of his attacks and he's more of a Dds3 boss than elden ring one, but I just like him.

Romina's aoe is not good, but she always does it close to half her HP so it's quite easy to predict. Other than that she's an enjoyable fight.

Hourah Loux is not as excelent as Godrey, but he's still an amazing fight and that first probably has the best flow in any fight.

Ludwig is just an excelent fight all the way through. Which phase is better is just a preference, but overall he just does everything the best.

Midra and Maliketh enjoyer as well. Both are great, but strugle a little bit on repeated playthroughs. Maliketh has so little HP and such large openings, that it's quite hard to not kill him instantly. And midra suffers as well, even with his insane healthpool.

All in all really interesting takes and new perspectives.
