I play (only) Goliath, and I noticed that it can be really hard to see the hunters and to see who is who at times. Like their names will pop on and off, and the hunters themselves are really tiny (one ends up chasing health bars instead of actual player models). I also feel like at higher levels the hunters have an advantage, but that’s another story.
My suggestion is: make a way for the monster to assign a priority target that is somehow highlighted during a bit fight? For example, if I always want to go after the medic first, maybe they get a red outline or their health bar flashes slowly or something. Could also make it so the monster can cycle them so he can “lock” onto a particular target. It just seems “off” to lose because of visibility and GUI issues as opposed to bad choice of target priorities or ability use.
