This approach of roleplay is very similar to my own. I tend to usually play a Mage on the first time through, since I find the options and variety to typically have solutions other weapon-based builds might not. Then on a second or third playthrough I play light weapon builds (Rogue-ish character) and big weapon builds (big dumb Barbarian-type character). Though once I got the Farron Greatsword it threw me for such a loop. It is just the weirdest and best weapon in so many ways. It is fun and interesting in a way I’ve never experienced in a Souls game.
Worth noting though, I have never gotten used to the weapon. Like, I feel like I get better with it each time I use it, but it is just so different that I have never learned or figured out the style. It’s not a greatsword, but it’s not not a greatsword, but it’s also a dagger (a bad one), and also a weapon with slide-y attacks as well? The special set of attacks is really weird and gives you low-profile properties, but also expands your ground hitbox and hurtbox greatly. Enemies like Pontiff or other enemies with high or mid attacks can frequently whiff while you’re in this state since these attacks assume a neutral stance. The last attack is a sword flip and will stagger just about anything, but it’s really slow and risky (and has a pretty precise hitbox to boot). One of the other things is that because of the weapon’s arcing and that it hits more reliably from the sides rather than front or back, you are generally better off not locking onto enemies. And that is really weird and takes time to get used to.
