Speaking as someone with 100 hours in the game at this point, I’ll tell you, the first few hours of MHW suck. Make liberal use of the wiki (the game is lousy at explaining itself) and try a variety of weapons to see if you can find something you like. It’s worth pressing on for a few more fights, certainly, to see if it clicks. If not, then not. Personally I didn’t really fall for it til I brought down my first Anjanath (or Pinky the Flaming T-rex as I call him) but YMMV.
