I don't want it the default running speed because it will cause direct harm to my playstyle. I use all terrain as much as possible for flanking and U-turning around pursuers as well as for stealth, I don't want to be booking it nonstop when I'm trying to be sneaky around people and etc.
I mean the climbing in this game is sadly not the smoothest there is, sprint makes it harder in some areas and may cause your death whether it be from falling off the map, or someone shooting at you.
Don't you even! You think you die, and that's that?! Huh?! You think you die an' everything'll be sugar and rainbows?!
