In league of legends, there is a loading screen that shows how how far someone is into loading, and they show it in percents.
My suggestion is that on or next to a loading person's name, show how far they are into loading so they don't get kicked for Afking when they aren't.
There's a visual representation for this. Players dot have their weapons out until they (almots) fully load.
If someone kicks you they are either impatient, stupid or you take too long. Showing extra percentages wont change that.
