If you try swinging a hammer around it's really difficult to change your momentum in a feint. I'm more of a grug smash kind of guy, I really doubt someone has the presence of mind to think out a strategy of moves, advance, carry out strategy while trying to adapt to what I'm doing (which is just grug smash mostly). If you're trying to do something fancy that looks like you're going to smash and then try to stab it'd probably be really uncomfortable and kinda slow. I guess I'd mostly assume both get a hit and smash is going to hurt a lot more. A hammer or club will explode their melon like... a melon. If it's not the melon then can I just smash again? Did they miss? Can I back off maybe circle around let that sink in and cautiously smash again or slip away? There is kind of a reason people don't 1v1.
