They kill so easily because I can never see where they are. Grenade spam is so prevalent because it is a viable method of killing folks, and why? Because you can't see the bloody things! Whoever makes claims that somehow this makes grenades more useful or the like... I can't imagine. Being killed by something that you knew was there but couldn't counter it because you didn't know where it was makes it a cheap tactic, where you feel you've been cheated. If you want to use an explosive stealthily, that's what remotes are for, and they are balanced in the fact they can't be spammed (take too long to put each one down) and the fact they have a sense of tactics. When you shoot someone these days, their first reaction will be to start throwing grenades at you. For the people shooting, it's good because it gives them an easy kill without worrying they will shoot you. However it reflects the player mentality that grenades actually work. And guess what, sometimes they do. Such mindless stupidity actually bearing fruit annoys me to no end.

Unfortunately, locus grenades in this game are like snipers - they have no real role on the battlefield, and therefore only decrease the overall enjoyment for everyone. But steps needs to be taken to stop this. You literally cannot see enemy grenades sometimes, even when you're looking right at them.



TL;DR:
Can I please see those damn grenades?

There is definitely some kind of bug with grenades. I've been killed by core locus grenades out to 30+ meters. That's a bug with the grenades or a display bug with the death screen.
