I hate fighting with anything but dual swords (although I have good aim as a gunner, who has the skill to shoot, aim, and dodge at the same time?), so what I do is get a really good weapon, and bring anything I can possible use: flash bomds, shock traps, etc. and I also make sure I have good defense and immunity. If you have poor immunity, it'll come back to get you I promise. And then I just wait where I know it lands at one point and lay a trap. That's why I do most rathalos hunts in forests an hills, because it always lands in 3. and then I put a trap on that narrow part and wait for the idiot to charge. Note: wind resistant armor is a huge bonus because he loves to fly around like a little retard.
