Im speaking for many when I say that the general setup of MCC is extremely flawed.
If halo 2 players wanted to play H3 or if H3 players wanted to play h2 they would search it. The H3 kids want their own seperate playlists for doubles and hardcore, and We want ours for H2. We're all tired of searching and having to deal with gametypes we don't want. It all should've been seperate from day one.
