@Tekato, as far as "one shot fests" go, at certain difficulties even a lowly grunt can drop you with one blast. At your level I know that you know this already. Ungodly amount of damage that can drop your fully overhealed Hive in a heartbeat is a regular occurrence with the way they jack up the adds in this game. CQC has always been a rock paper scissors guessing game to an extent and it just takes feeling out the Antagonist your battling to see what their tendencies are. I'm no god at this game, and I don't use a mic either when I play to coordinate, but I do try and play as much as I can in a team and avoid random matchmaking and that results in wins 95% of the time regardless of whether or not an Antagonist shows up. Sorry for the long post but I guess in closing I'm trying to say that I highly doubt Mercurysteam is going to change the way damage is dealt and the way the crits work and the cqc and everything. One of their main goals is to make this game super challenging so that's how it is whether we like it or not.
I'm fine with the AI one shotting since you can use cover and have ways to deal with them. But players no, they can easily get you behind cover and some characters don't even need to aim. One example is rak with shepherd he can just shoot his grenades at a wall near you, they will bounce and most likely take you out in one blast. And what I meant by the cqc is lag can make your grapples slow down or speed up to the point where someone can sneak up do a grapple and you won't even hear the sound, and there's a lot of cases where you punch someone right infront of you but for some reason it fails. This makes cqc inconsistent and unreliable.
