The other issue is getting across a map in PvP, since there aren't portals any more the sprint becomes a must to group back up with your team.
Sprinting could use a very slight nerf in PvP, where you would stop for at least a second once being damaged. But nerfing it too much would cause more problems.
Sprinting wouldn't be so bad if they fix aiming and make better dps on most chars as they had in gw2. Then could kill em on the run or before.
My sugestion for sprint
1st-After engaging in combat(doing damage), you cant use sprint until out of combat for 10 or less seconds
2nd- when using sprint and someone damages you, after certain damage threshold( like 20dmg in 1sec) or getting stunned, dazed gets you in combat state and disables sprint for said seconds
I've heard rumors that the hit box in the sprint is getting smaller, and if that's true, you have to fix it first
