I wasn't impressed, but I've only played each map once. The small maps are nice but it seems like there is too much crap in the way and too many corners to duck around. Could just be me not knowing the maps yet though. --- 99% of my posts are made from my phone so ignore the spelling/grammatical errors.
The maps are good, but the way Halo has been using DLC maps since Reach pretty much means you'll only see them in the DLC playlist. Just a forewarning.
Umm no, maybe if you cheap bastards bought them they would be more frequent. I see crimson dlc in bts and infinity slayer all the time even before that playlist was gone. It just depends on everyone in the game having them.
