Rathalos sucks to fight MHWI

I feel like it is so unfair to fight Rathalos in MHWI. I have to spend so much time chasing it around, and when I finally catch up to it, it just stays in the air and stalls until it can fly away and I have to resume chasing again. Not to mention how many attacks inflict poison and how it's fire attacks can combo you. It just feels unfair, and it sucks because I really want it's armor but it's so annoying to hunt
