Being able to hit a button and high tail it out of danger is cheap. I would be okay with accelerated movement if it built up over time, though. So, let's say you're walking forward for a couple of seconds. Transitioning can admittedly get pretty tedious, taking into account Halo's relatively slow walking pace. Instead of continuously walking, you could give yourself a jolt; instigate a jog. Press the dash button after jogging for a while and now you're full on sprinting. Speed should be gained in increments.
It allows you to make bad decisions, ruins map design, kills the flow of the game, makes callouts lets important, allows people to get away from fights, makes strafing more important. Thats off the top of my head, theres a bunch more things that make sprint horrible but people just see it getting around the map faster and the developers catered to that.
Let me guess. You run with a jet pack. Everything you complained about with sprint I think applies to the ridiculously over-used jet pack. That's what I think is the scourge of Halo MP.
Five million Cybermen, easy. One Doctor...now you're scared.
Every shooter now a days has a sprint (COD,BF,GOW) every shooter needs a sprint... Now this is HALO we are spartans super soldiers. Yeah lets leave out default sprinting... You guys are idiots for hating on sprint. You wanna complain about sprint ruining map design and aiding instant respawns? This isnt COD where.there are enemies.constantly behind you or next to you. Shooting and killing you before you can even aim
