Honestly it might be for the best that Halo 5's multiplayer seems to be faster paced and has more modern mechanics. Just look at what some of these critics are saying about the older Halo games in Halo:MCC feeling slow and not feeling up to date. If Halo 5 released with multiplayer that was similar to Halo 2 and Halo 3 several critics would rip it a new one. This time it seems like they're going for a mix of classic Halo MP and a mix of modern shooters that's less extreme with the modernization than Halo 4 was. And because they're doing a beta test almost a year in advance of release they'll have time to tune and balance things before release. Halo 4 was actually fun after they tuned and balanced some things and added some more classic mechanics after release, theoretically this beta should allow them to do the same but before release.

And for those of us Halo faithful who still love the classic MP, at least we still have Halo:MCC multiplayer. It's shame that we only get 6 Halo 2 map remakes though : ( Hopefully the community will make several more remakes with Forge and hopefully 343 will add them to playlists. Or maybe we'll get lucky and they'll remake some more Halo 2 maps as DLC afterall.
