You've got to be kidding me. Use a damn lance. Counter-thrust her sorry ass!
I'm online everyday during 9-12AM GMT+2 time. My name is Routsou; join me. Seriously, at this point, I can solo Rathian without too much trouble. Rathalos is WAY worse, spends half the fight airborne...
If you have some decent experience gunning... You can solo both of them... It will take forever but I've finished double trouble with both of them still up. Rathian was missing a tail and her head was damaged, and rathalos was virtually untouched.
