I do not understand these complaints. The drops even the playing field. Map control is still essential, because maps still have areas where you don't want to be stuck in.I remember in Halo 3 when a team gained map control, and the other team had no chance. Now, there is a chance. Grabbing better weapons does not make a team better. Also, map control is still possible. Holding down the ordinance drop locations, even with the drops containing random weapons, still puts the other team at a disadvantage. Now, to get a fighting chance, they have to out-shoot you to earn an ordinance drop to hope to stay in the game.
Every Halo game has started players off with a good, long distance weapon. In Halo CE it was the pistol. In Halo 2, it was the BR. In Halo 3, it was the BR again. In Halo Reach it was the DMR. Now, In Halo 4 you choose between the DMR, the BR, or an Assault Rifle. What is the problem?
Sure, in past Halo games you started with an AR or SMG, but no one liked that and never voted for those gametypes. All the loadouts do is give you choice.
Keep in mind that all of this is coming from someone who was very worried about a lot of these changes when the game was nearing release. Also keep in mind that this is coming from someone who is a big fan of Halo. It's still Halo, yo.
