While @FierySlayer117 has a good point, I’m in full agreement for having your teams deployables highlighted. When you’re busy killing the monster and concentrating on dodging his attacks, you tend to forget the exact locations of ALL your emplacements.
It’s like when I play Maggie. I setup a spread of harpoon traps so that the medic/support have a place to fall back to. Sadly though, I can’t remember the exact placement because I’m concentrating on not dying, so I have to vaguely tell the medic or support to run where I ping.
In the medic/supports shoes, I know for the fact that they’re praying to the Evolve gods that I’m right. Otherwise, it can easily cost them their lives and the game as a result. The highlight system wouldn’t have to be revealing deployables at all times either. Just something as innocent as 30-60m (half to full dome distance).
Giving highlights to deployables will make it much more manageable to direct fellow hunters where to run for your setup points, and eliminates the possibility of confusion and frustrating mistakes.
