For those talking about clunky controls - here is my interpretation based on witcher 2 (which applies to W3 but I think they made controls significantly improved)
In a dark souls or bloodborne, being pure melee is a viable strategy in its own right. so if you want to master swords, you can use that to attack almost every enemy in the game - its just a matter of learning when to strike or dodge roll etc.
So in bloodborne for example, its explicitly designed for you to be aggressive and if you are melee focused then mercilessly destroy enemies with melee attacks (at the right opportunity) - if you ahve the stamina and weapon for it, its actually a good thing to go all out and just melee hit the enemy in rapid succession, thats a viable strategy and character build
in W2 the game was balanced for the combination of sword combat and the signs, so pure swordplay was deliberately designed to be not-enough due to the enemy types (eg shield users who block your sword attacks) a bit like how RPG's have balanced party members, not just all fighters (mage for damaging ranged AOE spells, cleric healing etc)
W2 is designed like a turn based RPG mechanically, eg they would show "geralt attacks monster X for 7 damage" and they didnt want you to just melee attack enemies in majority of cases due to that becoming repetitive real fast (eg limited number of special move types/combos versus pure action games like DMC)
this is similar to how gothic and risen games are stat focused first and then action oriented second
Having played all the games mentioned I understand this but there is some noticeable input lag and at times controlling Geralt feels like you're trying to guide a balloon underwater.
