Guess you didn't read that I just said, "I know these are not concrete facts." It's what they have revealed to us. Sure, not all devs stick to their words/promises, but it's not entirely unreasonable for a fan to be excited about a game that the very developers describe to us. It's our only source of solid info...sooooo let us be excited.
Halo 5 beta MP reveal:
--focus on arena gameplay
--Fair starts
--Weapon control
--Map control
--Mentioning "competitive gameplay", harkening back to the Halo classics.
They all say this to try to appease the fan base, because they know we were unimpressed with Halo 4 MP. Who's to say, sprint, dash, boost, and spartan ground slam can't be balanced or competitive?
