Game finally got hard, lottery style... you don't have time to react anymore.

I play FPS games, CS:Go, Destiny PVP, Warzone, alot of fast reflex games with fast TTK and athletic movement, where you have under a second to live or die. Some mercs in the game can kill you faster than a human can even perceive and even offscreen. Maybe the scaling is a bit off, but why do they end up sucking vs mobs, because I have a workable strategy I use to kill any merc. I use Ballista Totems, I plant them, walk away, they do the job offscreeen, almost like a miner. Sometimes my totems just evaporate instantly and I'm like, yeah, not even bosses can do that shit, I just walk away from that...
