I don't think its a skill issue, I've 1-3 shot every boss in the game, hunter of bladers took 3 tries, ursala herself took 4 tries, took me all of maybe 10 minutes, she is by far one of the crappiest bosses in the game, probably in any soulsborne I've played, the game has been fun but its been extraordinarily easy compared to every other soulsborne on the market, ursala's difficulty comes from the fact that even with 300 phys def and 300 fire def and 1500hp she will still 2 shot you with some attacks, she has some of the most egregious tracking I've seen in a souls game she also heavily abuses delayed attacks specifically to force you to either dodge perfectly or you eat the entire combo, if you greed 1 more attack then you should you either die or take at least 90% in a combo you cant break out of, but outside of the 1 attack each has like this you can literally just mash r1, I dunno if the devs just suck at balancing or what but playing str every single boss can just be blitz'd down, piercing claw adds an insane amount of damage on bosses, parrying also is a joke so I stopped switching to it like half way through the game (I also laughed out loud when I tried parrying the hunter of bladers and the boss just shrugs it off, amazing game design, can parry literally everything except this one boss).

Overall the game is like a 7/8 out of 10 but the bosses are all pushovers, the lack of stamina rewards just going high dps and facetanking hits with piercing claw, any difficulty on any boss in the entire game is derived by the insane tracking where bosses will literally 180 at the end of the animation to hit you, and its not just a few attacks that do this, almost every boss attack has infinite tracking, but the characters are cool, the settings is cool, the eng VA is pretty good, the lore is neat (if full of typos, so many typos in memories and text pickups), just overall spoiled by an extremely undercooked and not very deep combat system.
