I feel like everyone should be walking / running in different speeds, because lets face it if you chase someone who has 2 yards on you it will be an endless chasing game until someone lags or gives up.
For example : Kevlar make people move slower, leather armor a bit faster
- Amount of stuff you have in inventory , obv more stuff slower you are.
-Armor you’re wearing
Now I am not saying that that there should be a dramatic change so some people will be running in crawling speed and others flying, but just enough change so there will be different factors during a chase.
Another suggestion is when you hit someone in the legs they move slower or if you hit them in the arm they reload/ swap weapons slower.
