Are you putting in an opinion on a game you don't even have access to?
If you were to play literally any of the halos, you'd know each one has its own feel to it. Halo 1 had the H1 pistol, H2 had it's own feel for the BR and sniping, Halo 3 also had its own feel (think MW2 to MW3 sniping for instance. Totally different), ODST and Halo Wars were completely unique in their own rite, Halo: Reach changed the game entirely, some for better some for worse, Halo 4.. Different in a bad way, H5 is now improving upon everything in a unique way. The entire Halo 5 system was executed in a very positive way for the franchise, and you would know that if you actually played the games you were talking shit about.
Also, in case you haven't been told enough, your [b]incredibly uninformed/stupid oversight[/b] is incorrect. All DLC for Halo 5 will be free, and after many mistakes 343 seems to be doing right by their players. Something Bungie [i]used[/i] to do.
