1) "Oh no, the game became too difficult on very hard!! Help me, it's unfair!!!"(c)
I started a new game a few days ago, on very hard difficulty, playing without any investment into perks or attributes (just not spending them, not a single one), already lvl 23, having no issues. So complains about difficulty are meaningless. I'm lvl 23 already without any issues and without perks / attributes.
2) "Stealth pistolero is dead since revolvers can't use silencers anymore"(c)
Stealth pistolero is still absolutely viable, just have to take right perks and keep gear up to date, maybe dump some "PAX" + "EQUALIZER" mods if one is unable to oneshot in the head.
3) "Netrunners are useless now omg"(c)
I disagree, I would say they just have to adapt and start using smart weapons for takedowns and use daemons as a "debuffs" instead of damage. Tried it as well and it works and playable and enjoyable.
4) "Performance is terrible my game lags"
Performance is top notch on my machine at the moment (i'm playing on linux, ubuntu), much better than before, more so I would say each major patch performance of the game became gradually better for me, so it's probably something very specific and cannot be generalized by saying that this patch made it worse.
But I do have complains as well:
1) controller tips and controller - focused gameplay in general, its annoying for PC user
2) bugs here and there (double quest rewards, can't toggle sneak)
3) crafting is sooo dead. I never really enjoyed crafting a lot, so it's no a huge hit for me.
4) broken loot drops are not "highlighted" by a scan, which makes them hard to loot. Either remove broken drops completely or make them visible
5) not really a big fan of purely "lvl based" progress (reminds me of Skyrim for some reason - you are getting only shit early, you are floating in gold and legendaries later on). Most of the gear appears in stores based on your character level, an not out there, in the world. Being able to get amazing guns and gear as early as possible is a fantastic thing in open world rpgs, a lot of players enjoy beating "unbeatable" opponents just for the sake of challenge and good gear. To some degree one could give an agrument - you can get iconics, they will be usefull through the entire game, but the problem is - vast majority of them are locked behind the "heist" quest, so untill then you are forced to roam watsons with whatever you found / bought at the store.
6) some perks are wierd, for example - the perk that reduces charge time for tech guns. Since tech guns now are heavily focused on "bolt" ability, making a dynamic and stackable charge time reduction just messes up the timing that you are used to. More so, some guns have very low charge time which make it almost impossible to consistently land those bolts.
