I've been playing my for like 20 years, I'm fine with the anticipation part in general it's just stupid for parrying. The time spent waiting for an attack you know is coming is better spent setting yourself up elsewhere as opposed to risking winding up a slow parry. Obviously weapons like longsword were built with that in mind so that's different as it's part of the intended play style.

Perfect block is fine since it's quick enough that it works as it should, but there are a number of weapons that have extremely slow parrys.

I get that and for 99% of monster hunter it's fine, but a parry should be like a guard/perfect guard for weapons that can't block. Those are quick responses when you're in a situation you know you're going to get hit in. With wilds the majority of the parrys are like 1-2 seconds of winding up when you only have a half of a second to react.

Something like longsword was built for this, so the gameplay is about waiting for attacks, but every other weapon isn't. The time spend waiting to parry is better spent moving yourself into a better position for something else.
