Best tip I can give you, is ways stand on a freezing trap while leveling. This will give you time to get to maximum range, then you can open with aim shot if you have it, followed by concussive. They start to get close, scatter or intimidate. It sounds like you know how to kite, which is 90% of the skill you need for world pvp leveling / surviving a gank.
If trap resists, then you have scatter or intimidate. Wing clip and raptor strike can be cast at the same time, so macro it. As soon as you get out of the dead zone, hit him with concussive shot.
It sounds like you already know what to do tbh.
Edit: If you're BM and a marks hunter attacks you, close the distance with intimidate, use your axe and stay on his back. He'll win a shootout, so don't have one if you can avoid it. This also works on many casters.
