Here is what I tend to see on my screen (an example someone else took and is the left image).
Perhaps we could use the TTM mod to make it easier to see... otherwise that image on the left easily becomes hidden or near impossible to see on most maps.
You can get the mod
here. It does have bright skins in it but the server admin can permanently disable it. It is disabled by default but people can still vote it on unless the admin disables it. This is more of what I was hoping we could get on the server with a setting or a mod. I dislike bright skins in the essence of those annoying neon ones. I just would like to be able to actually tell if I am fragging my own team mates or not.
