Well what I meant by DkS vs DMC is that DkS has a smaller moveset pool and you need to be calculating in every attack or suffer major consequences, where DMC you can go slash happy with a variety of high hit-count combos and jump/dash around to evade quickly. Both have their merits and require skill but I was comparing the style of action gameplay.
I disagree that the weapons play similarly in MH though. I can't think of any melee weapons that have a moveset similar enough that it would cause you to play in the same way. The thing with the lower move count though is that every move has its use and place in a fight, whereas in faster paced games it might not matter what attacks you use as long as they fit within the window of opportunity.
What I completely agree with you on and understand though is that MH isn't instantly fun. Faster paced style hunting games throw you into it right away and you can easily adapt due to the leniency and similarity to other action games. MH has a long long learning curve (10+ hours) your first time and boring tutorial fights at the beginning. But even 20% into the content though you'll be fighting nothing but large monsters for every mission. Honestly considering your action game preferences, 60fps advocacy, and platting of them I think you would enjoy MH if you ever gave it another try and got past the initial hurdle. Not to plug myself here but if you take advantage of the invincibility frames on dodges you can find the gameplay faster and more skill based
