Halo 5 is cool. More Halo-y than Halo 4, despite sprint and thrust.
Sprint in a Halo game is scust.
Go play halo 2 or 3 taco
Those two games are a lot better than anything that's come in the series since then.
Halo was a great series when nothing on consoles could actually compete against it. Many people considered Goldeneye and Perfect Dark to be the best console FPS games until Halo 1. Going from a game that controls like absolute shit and is incredibly slow (Goldeneye or Perfect Dark) to a game that controls great and feels a lot faster (Halo) was a huge leap for a lot of people.
A lot Halo fans don't get why Halo became popular, it controlled and played better than other console games around it. It wasn't because of weapon spawns, weapon balancing, MLG shit, it was because it was the best thing console owners can get control wise and speed wise. That's why CoD beat the shit out of Halo when it comes to relevancy, it played better and smoother compared to Halo.
Console owners en masse don't give a shit about weapon spawns and tons of tiny things diehard Halo fans cry over. They want a game that's easy to control and feels smooth. Halo has felt officially crusty since Halo 3, CoD 4 multiplayer felt like a breath of fresh air compared to that ole Halo styled jank. My favorite multiplayer game last gen was Rainbow Six Vegas 1, I'm sure as shit not going to cry and bitch because janky tactical shooters died out.
In essence, Halo was only "special" when nothing competed against it. Nowadays? Halo is just one game in a pile of FPSs.
