Is it worth getting monster hunter unite if i already have monster hunter2.

i was just wondering what are some new features in unite that monster hunter 2 dont have.

Can i jump straight into MHF Unite without actually owning MHF2 ? I mean is it an expansion or im still able to start anew in MHF Unite?

yeah its worth it if you are close to killing akantor or have killed him, his set gets nurfed pretty hard in unite so dont worry about making all of it, just move onto unite. akantor is the urgent for guild HR6 i believe. and if you are having trouble on him use gun chariot ;)
