His moveset got upgraded but his speed has been decreased. Same for his power. It's about half of what it was in MH3. And he takes longer to recover from attacks as well, leaving him open for longer.

Other than his upgraded moveset, which has some nasty moves I must admit, I think he'll be easier in the end than he was before. That's usually how it goes with MH bosses. They become easier as the MH series progresses. Like plesioth, he got nerfed more and more throughout the times. Compared to MH1 that is.
