I know some of you guys don't care about this stuff, rightfully so, but it would also go a long way to making 343i/Halo look somewhat good again if all the maps were free.
It's a smart/logical practice, but also not a very common thing that occurs when you have stuff like BF Premium, CoD DLC map packs, etc.
Could help jump-start a turn-around for their image. Again, I know some of you guys don't care about this stuff, but for me personally, it would be nice to enjoy talking about Halo 5 without constantly being reminded I'm a "sheep" for supporting them after MCC.
