Well, to each its own I guess.
I wouldnt mind, but I am a kind of completionist, I usually want to SEE EVERYTHING in a game by the time its over. I rarely do a second playthrough. So it takes me a while to complete a game. Also, that is why it takes me HOURS to create a character (ME games were a BOTHER, no chance to skip prologue to custom and fine tune your avatar - what a bitch!).
If others want it and devs have time & resources to spare then why not? I personally always prefer to gather cool lookin gear rather than max out. For me its always a compromise between design and stats.
In dragon age games I found myself using inferior gear because those legendary items looked gay.
BTW I must point out that OP wrote he doesnt buy games without NG+ feature... with TW being an exception. So, do you really need this feature to enjoy The Witcher series?
I think you already do
