Not the ones that i have encountered so far.This is kind of what sharpshooters currently do except for the shield grenade. They stay in distance as long as they see you. They only approach your last position if they loose sight on you. If you are too close they switch to sidearm(not always tormentor). If their shield drops they take cover and even run in the opposite direction.
They all tried to get as close as possible, follwed me up a roof where they then flushed me out with grenades - just like the Commando. They all behave exactly the same.
Also...look at this:
Does this look "fair"? It even oneshots WITH Shield up. And thanks to the Scope is has a very tight Spread, which gives a higher chance to hit. If you miss with Exe, you deal 0 damage. If you miss with this Shotgun, you deal atleast some damage. The first shot at 18s? Yeah, thats usually the engagement Range that i use too. Yet the Exe cant oneshot through Shields.
It looks really nice to draw shapes into icy-ground though.And of course, if you hit a person on the ground with a Class 3 beam laser, it should instantly kill them and put a small hole in the ground, unlike the current 20+ hits to kill somebody.
