Through out this summer, I've played nothing but Halo. And I played and past Halo 3 and ODST solo on Legendary twice, Reach on Heroic solo, and Halo 4 on Legendary solo and I notice I have better skill and became a better Halo Player in MatchMaking. Now I'm good with precision wepons at long range, and I Snipe way more better then I used to. It's pretty shocking lol. I did plan to play Halo: CBA on Legendary but I'm exhausted. And I will NEVER play Halo 2 on Legendary... my god, that's like your in Hell and the devil forces you to play that forever lol. :'(
