If you don't have stamina regen and in no condition to fight you're pretty much dead. My point is that if you've made the decision to run, spending a few extra seconds circling/evading to build up stamina is generally better than trying to run without enough stamina to break LoS.

Avoiding enemies/hits is fairly easy, even against multiple enemies. Engaging in combat against multiple serious threats is less so. A mistimed attack instead of a block/dodge, or a missed parry if you're relying on a buckler can get you staggered and/or ended quickly. Dodging, circling, moving to avoid strikes is pretty straight forward and provided you're not under serious de-buffs (wet and at night) then getting enough stamina to get away doesn't take very long.
