Halo games have always been a medium paced arena shooter. They have always been on the slower side. But, if you give players an accurate, fast killing, and hard to use utility weapon along with supporting weapons that fit in their niche and are viable options to actually pick up and use; the game becomes much faster.
I don't think default sprint inherently makes the game faster, but makes it slower. Now they have said that getting shot while sprint makes you slow down. But, in the E3 and RTX videos I haven't really seen that stopping power effect be very useful. Sprint just seems that in my opinion is a get out of jail free card, because in Halo most weapon battles last more than a second or two. In turn giving someone time to turn and run. Now if the stopping power is akin to Gears 3 stopping power essentially making default walking speed faster than rodie running, I'd be fine with sprint as a default. Mostly because it can only be used as an offensive ability and not as a defensive strategy like Reach.
I just think if 343i buffed the utility weapons instead of constantly nerfing them, and buffing the other weapons accordingly the game would play faster.
Then again, this is just my opinion and I won't know for sure until I actually play the game for myself and see if sprint is bad in Halo 4.
