[...] I don't recall an enemy with a tech weapon blasting me through my cover. If they could it would be extremely annoying to play (e.g. "enemy tech sniper tracks and starts blasting you from the other side of a building, and there's nowhere you can go where they can't shoot you", "enemy netrunner uploads 'suicide': you die in 10 seconds"). I wonder whether a good rule of game design is "if the game would be stupid if the AI used the same abilities of the player, the game mechanics need work".
Eh? There are actually quite a few snipers who can blast you through cover with Nekomata sniper rifles. Off the top of my head: 1) the sniper at the cop event where there's the Russian chick with the fast movement who was hired by cops to get rid of homeless people (near Cassius' ripperdoc shop), 2) the sniper at the cop event in the city where you have to climb up to a sizeable area where a whole bunch of criminals with a guy who's been stealing from Trauma Team (sometimes there's a Trauma Team AV there), 3) the sniper at the cop event where Biotechnica hired goons are breaking a strike. Quite a lot of them actually. You can tell with them because you see a red laser homing in on you when you're out in the open, and if you sit in any cover for too long they
will hit you. It means you can't always sit still behind cover and hack away merrily, you sometimes have to move. It's actually quite a good counter to the OP netrunner problem you talk about, but they don't quite make enough of it.
There was a discussion a while back about the missed opportunity with netrunning, where any sizeable group should have a netrunner you have to have some sort of "duel" with. I would suggest a minigame of Battleships type of thing, or at any rate
something to acknowledge that there are netrunners out there who are as good as you are and can give you a run for your money. Some of the enemy netrunners are buried quite deep in their nests and can pump out a steady stream of Overheats - which
would be a problem if you didn't have almost infinite health stims. Also, I don't think they have to be jacked into anything, they are mobile with their hacking the same way as you are, and actually do move around sometimes to avoid your hunting them.
Weirdly though, all these enemy netrunner shenanigans are front-loaded, they seem to dwindle away the deeper you get into the game.
