There have been times where I am playing a heavier hero and someone on the other team is playing an assassin and we are on the same point. They just keep running away from me. With their higher sprint speed and some characters not having very good ability to catch runners, I just sit there or keep trying to chase them. I think running away from fights to prolong them till help arrives. Or another situation could be where I am fighting an assassin and they are one hit from being dead and they just run away. I cannot chase them, Even if I was using a character that had the same sprint speed. There are a few characters that are very good at catching people who run such as shaman but I do not want to switch characters just for that. Maybe there could be a system implemented where the normal sprint speed is affected by the current hp of a hero. A damaged hero will run slower than the same hero at full hp. This would just be a mechanic to prevent tag and force people to fight. Similar to how in tribute or in breach, the person with a banner has a lower sprint speed to push them to fight for the banner.
