I'm not familiar with this Quartering guy, but Kallie went ahead and admitted that she passed on a substantial portion of the game-- barely doing side quests and refusing to do NCPD missions because she doesn't want to help the cops... And then she admits never upgrading her weapons
That might be a case of most commenters not knowing what they are talking about. But on the user, not the reviewers end.
Listened to the two 'in depth' youtubers reviews that were recommended in here. Listened to the Giantbomb Jacking In commentary video. Played The Witcher 3 for 150+ hours -- to the point where I really, really got to know the games systems - and I know what she is talking about.
And its nothing like most commenters want to make out of it.
Upgrading weapons and gear - is 'a worse optimizing strat' than the usual min/maxing you are engaged in, for when you mostly like the look of an item, and want to keep it. Its not the min/max optimum - and the way the game scales loot, you are getting better gear all the time. In addition to that - some of the upgrading materials are rare - so you might want to keep them for the endgame.
On the sidequests front, she admitted to barely doing 'contextual situations' quests - where quests would pop up, because you were in proximity to something. Knowing how that 'pull in structure' was implemented in The Witcher 3 - it wasnt great, it was just a 'hey there is something here' tease, that never quite pulled you in. One or two throw away voicelines, thats it. Didnt mean, that the quests behind it were bad, but the attract structure was nothing special. If they've kept it roughly the same - I can entirely understand why a reviewer would skip all of them, presuming, that they did other sidequests. (That 'attract' structure is not the only way to get sidequests in The Witcher 3).
On the 'did not do any crafting' front - if its set up like in The Witcher 3, crafting is level scaled, with 'top levels' for certain gear, but also scaled - so you never get high level crafting recipes, you'd actually be interested, that are much more than 2 levels above yours. Which means, that they tend to become meaningless, because you are advancing levels faster than trying to gather stuff for specific recipes would be worthwhile - considering the time commitment - and while you'd be gathering, you'd be leveling and...
The actual loop in The Witcher 3 is "Best weapons drop scaled as quest rewards - rarely." At least once you are overleveled for the general level cap of an area. There are about 5 different 'perk groups' for weapons that make sense - and there are about 20 perk groups in total. So loot is mostly useless (same with crafting recipes), until you hit one of those - and then it is not.
So if CDPR copy pasted systems from The Witcher 3, which hearing about all the systems they have in place from reviewers seems like they did --
ALL of those are valid criticisms.
So if you are getting all 'rallying cry for reviewer is stupid' about it - it might turn out, that you just dont know what you are talking about at all.
