It sounds like you need to force more discussion in session 0 talks (or earlier). Do you want an RP-light, fairly linear game? Great! You're not alone. But everyone at your table needs to agree to that, or at least one of you is not having a good time.

I like a good hack and slash dungeon crawl. I also like RP heavy games. But those are two very different games, and it's good to have consistency within whatever game you're playing.
