Long shot, but does anyone play [MHP3RD]?

I'm looking to play MHP3RD with someone, grinding for Duramboros horns. The fight drags on, seeing as I'm a gunner, and of the few times I've done the quest, I've yet to receive any horns. If, somehow, someone plays this game, I'd love the help. I'm using the PPSSPP emulator to play the english patch version of the game. I'd also like to use discord to communicate.
