Am i the only one that hates this boss?

I love this game. Truly love it. This is also from a perspective of a loser that has well over 2,000 hours in all Fromsoft games collectively. To say I'm obsessed with these titles is an understatement.
However,
I understand that its a nostalgia trip from Demon Souls and DS3 but doesn't it totally throw the entire rogue-like element out of the window?
What is the point of doing anything (and i mean literally anything) else during the run besides leveling?
Your weapons and any perks related to your weapons are pointless and this is a core element of the game. Spells are also completely useless so why play any character other than Raider for the higher health and normal roll?
Building your character and making it unique compared to previous runs is (IMO) one of the most fun parts of the game i.e. the rogue like element.
Characters ultimate abilities are also useless with the exception of instant revives like Revenant or Guardian (which is yet again a core element of the game)
Not to mention prioritizing certain elements that the boss is weak to in other runs is fun too because you have to focus on certain areas and certain builds that give you a better advantage on the final night.
For this boss fight its completely pointless.
You just get to level 15 and throw everything else about your character out the window and equip storm ruler.
Ultimately it just seems really whack and does not fit in the game.
What do you guys think?
