It's got a similar issue as The Witcher 2 in that the combat is a bit rough around the edges, mostly in terms of hitbox consistency both on enemy attacks, your own, and dodges, and the early game is skewered against you as progression slowly skewers it back in your favour until you become an overpowered monster. Obviously, compared to Bloodborne, a game built almost entirely on the backbone of a combat system, a game like Wild Hunt can't hold a candle to that level of combat game design mastery.
Like most CRPGs it's about the sum total of parts. The world, the dialogue, the lore, the quest arcs, making choices, discovering points of interest and surprises, and immersing yourself in the adventure. All of that is really subjective, so you'll either love it or you wont. The idea that WRPGs suck after the Souls series is utterly laughable to me. In one or two specific mechanics, sure. But they're worlds apart in vision, scope, and concept. They're about as comparable as Mario Kart to Gran Turismo; genre similarities only on the surface, the games themselves operating under fundamentally different design from almost top to bottom. Apples and oranges, to put it simply.
That being said, improving your Wild Hunt combat experience involves embracing the versatile tools and abilities at your disposal. Wild Hunt =/= CRPG (or any RPG) where a specific build is required to use magic, melee, or potions. All of these things are immensely useful by default, as this is Geralt's character. Your build choices ultimately supplement abilities, not define them. So if you're having a hard time with combat make sure you're abusing signs and potions, and oils too, especially early game where those buffs can make a huge difference.
But yeah, in the grand scheme of things Wild Hunt is what it is: a massively open world CRPG with a strong focus on narrative and adventure. The combat definitely could use some work (again, those fucking hitboxes), but treating it like Souls/Borne is going to invite in comparisons it'll never, ever be able to live up to. And vice versa, too. Souls/Borne questing linearity and simplicity is borderline non-existent compared to the narrative web of characters and arcs that a good CRPG can provide. Which is understandable given this is a cornerstone of the genre.
Wild Hunt is no only my favourite game of the year, but one of my favourite games ever, warts and all. Coming from Bloodborne, if that tight gameplay focus and loop is what you're after, I can definitely see how it would disappoint. And if you cant shake those expectations and get into what Wild Hunt is all about, then maybe it just isn't for you.
EDIT: Disliking the quests is telling that this probably isn't for you. I fucking adore most of the quests in Wild Hunt.
