I have to say this for Ragnarok, I've played a number of customs games on it with no mantis, BR or carbine + magnum + frag starts. No personal ordnance, weapons like Halo 3. It plays amazingly. None of the previous problems. I really do believe that sans-DMR and personal ordnance Ragnarok is an amazing map, as Valhalla was in Halo 3. But for standard MM, I never can really enjoy it.
Played another game last night, our team won top control. They were down by several people but it was an 8 v 8 by 30 seconds in. That brief advantage gave us top control for the rest of the match, and this wasn't a team doing this, it was me, a friend, and randoms. beat them by a solid 200 points. They never made it as far as the halfway point between the bases.
