Spamming attacks with a slower weapon (Halberd) doesn't seem great since the weapon targets the last area you were facing even when an enemy moves around you, might be changed at the end or kept this way. Same with weapons, heavy weapons are the same (Mostly, I will explain later) slow but strong and fast weapons are fast with less dmg. Targeting is odd with some spells but it might be intentional as some blasted an aoe off target but still hit.
Interaction with the enemies is good but the new heavier (Slightly delayed) feeling to the attacks and rolls takes time to get used to in comparison to both souls games before it unless your a duel swordsman in which the speed feels right at home. PVE - I will try and stay away from what was already said, you can take my word for it that everything said about the game so far is on point.
