Yeah, one of the most infuriating things is how no matter how far away from him you are it takes about half a second for him to hit you with his homing talon. This is deadly when you are across the map and think you're safe... NOPE! When you're very close to him it's not so bad because you expect to be in danger and it takes the same amount of time for him to hit something directly beneath him and something on the other side of the tower top, for example. If he could only move as quickly as when he does the flying charge it would be more reasonable.
As for the tail swipes, you just have to assume that any time he does the sideways reposition (dunno a better word for it) where he dips down and turns ~90 degrees and ends up at your side... just about every time he chains that into an untelegraphed tail backflip. The biggest BS though is when he just does the untelegraphed backflip at random.
Also, every time he roars he shoots a fireball right in front of his face as he takes off, so if you suspect he's going to roar get away from his face as fast you can. YOu also have to be careful about being sort of in front of him while he's in the air because he likes to do a midair side chomp that blasts a bunch of fire in front and below his face, similar to rathian's side bite while she's on the ground.

Still a more difficult fight than it was in 3u, but not necessarily for the right reasons...
