Participated in MLG back in the Halo days and while I'm not likely the best candidate to opine about which shooters are the most respectable, Halo 4 is the least interesting/competitive of the online MP Halo games. But then again, I thought Reach was either the best or second only to Halo 2 and apparently MLG outlawed it as well, so eh.
Halo 4 is way more balanced than Halo Reach was.
Eww Halo Reach
Yup, its true.
If you exclude the Boltshot, Ordnance drops, no health bar, and even more OP DMR.
