No doubt that Mosh 1 is one of those 'really hard but once you learn how to play it you feel stupid for thinking it was so hard' things, there's not much I can tell you to help other than to just strum along with it in time, and drum your fingers down the two scales. I noticed that I drum my fingers at my desk in school now... ._. I've also gotten back into GH2, I FINALLY managed to 5* everything on Hard (The Trooper is stupidly frustrating), and have a few songs from the last 2 sets to 5* on Expert (Psychobilly, Carry me Home, Misirlou, etc. Somehow, I managed to 5* Free Bird though. O.o)
