I think this is only really a problem in Little Crusaders, but if someone has a high ping, it can be hard to see it on the pink background if they’re the dragon. My suggestion is to give it a dark background/outline to make it stick out more.
I threw this together, it’s harder to see in game when the numbers are smaller and you’re usually looking at a quick glance.
Edit 3 hours later - Just found someone with high ping in the wild, hopefully this better explains it than the little graphic I made.
