Sprint belongs in the game, but not multiplayer. I've been saying this for years now. What set Halo apart from any other game or franchise was how unique it was. It was the only major franchise with a significant shield, never had sprint, and never had any stupid abilities. Halo is unique because its always been the only game where true skill can shine. Only power weapons are 1 shot kills. Normal weapons like a BR take a steady finger. This is not CoD where whoever gets the drop basically gets the kill. Halo has always been the game where you have a chance to Ninja someone or out BR them.
Halo 3 lasted 6 years. It had a lot of people that continued to play it even when Halo Reach and Halo 4 came out. The reason this was because it had the core fundamental differences that Reach and 4 lacked. It had that basic feel that no other series had. There weren't people flying around with exo suits (except the modders LOL) and you were not dying instantly by anyone. The weapons were balanced. What sets Halo apart is the ability for a skill gap. You can pick up BF and CoD and be good instantly if you can aim. Halo always took that extra step to kill someone. You needed to be consistent and smart.
I think that things like clamber and everything else belong in the game. Definitely campaign, but not Matchmaking. Maybe there could be a playlist that has these attributes, but the core aspect of multiplayer should not involve things like this. Halo 2 and 3 lasted so long with these basic pieces. Maybe some could be incorporated into Halo 5, but it should not be a total evolution. Reach and 4 were pathetic. Barely anyone played them. The attempt to modernize and appeal to other people is a noble marketing attempt, but it is flawed. As a business major, I know that Halo cannot have these similar things. CoD already dominates this market. If Halo were to change, they would be beat out and lose their fanbase. Halo needs to stay unique. Almost nothing was as big as Halo in 2009. Think about how much money there would be in the tournaments now that everybody is an eSports sponsor.
Please put Halo back to its basics. New changes have been proven to fail already. This is not CoD, it is Halo.
