I'd love to join up (and maybe even do the Nightfall), but as of now I'm still a level 26. Maybe when Xur shows up I can snag a piece of exotic Titan armor and hit level 27. However, I was soloing the Nightfall yesterday and after 40+ minutes of fighting and then the disappointment of being returned to orbit after wiping, I noticed that the keys to winning would be: (1)another player (2)VERY conservative playing (3)finding cheap spots to fight the boss. Luckily I was able to do 2 of those things, but honestly, at level 26 it's unbeatable on solo. There's no way to do it (by yourself) without the Nexus murdering you. So anyway, keep me updated on your plans...
