Taking down that pink rathian and then easily dispatching nergigante has really helped me with this game. Speed of her attacks and having to get them down to counter them has helped me with nearly every other "normal"class of monster in high rank, they all seem so damned slow by comparison. I used to feel I couldn't take the high rank monsters down myself but I just went face first into a few of them last night and downed them all without a single faint, though I haven't tried diablos. normal diablos is a pain for me for some reason. I think it's his massive invisible hitbox . Still have yet to face anymore elder dragons though as I'm looking for their tracks, so I'm sure they will put me in my place.
