Yep, an advanced "beat em all" system would be welcome in Cyberpunk 2077, seeing how bar-fights and agression are common, there will be a lot more close combat than in The Witcher, so something more "developped" about hand-to-hand would be welcome, mostly that most of the time you won't be able to rely upon your gun (like in a club or something), it's noisy, and once you shoot a few bullets, you can be sure that everyone will get their gun out, same when you'll get in Corporates buldings with high security, you'll have to fight your way untill you get your hand on a gun, your gun can jam and you'll not have time to fix it, you can run out of ammo, etc...
I figure too that sometime you'll be looted, stunned, etc... and will wake up in a trashcan without any gun on you.
It's better to know how to fight and never have to use it, than don't know jack about and get screwed because of it.
