Byshyno20 Infinite sprint was disabled intentionally, yes - and likely will not return unless there’s a stronger justification than “it’s uncomfortable.” You're a good player, you'll adjust quicker than you think.
I agree that infinite sprint paired with no jump fatigue is superior feeling movement in BO2, but it promotes excessive and unnecessary jump abuse.
BO2 was also not really written with bunny hopping in mind that this combination enabled. Consecutive jumps frequently bypass the grounded movement state, which in turn breaks landing animations and causes the player to appear frozen between jumps, effectively looking like they’re floating.
It came down to removing either infinite sprint or no jump fatigue. No jump fatigue was kept because it improves immediate, micro-level movement control, while infinite sprint mainly affects long-term movement uptime.
But like Dec said, you can't please everyone.
