OK I'm tired of this LAG Crap. Half life is so Outdated, not to flame anyone and their computers, but, please, they invented upgrades and jobs for a reason.
This would be a good thing BECAUSE Multiple POWERSTRUGGLES, you don't know if your teamate needs help. Now if theyres a big nifty glow when one hits another, you could be like OH ****, Vegeta needs help, teleport over there and go go.
ESF should fix what issues they have now and not worry about adding eye candy, the requirements will always be the same requirements as the Half-life box. If you don't have them, well sir, you are ****ed.
