One of the regular complaints that comes up is how the telegraphs can be hard to see based on the arena color.

I’m not sure why a) we can’t recolor them to our tastes or
b) they aren’t more 3-D (like the purple “a fight gon’ spawn here” circles we see in quests) or
c) use 2 colors. So it cycles red and blue or some other contrasting colors between each pulse.
