You mean... Pressing R to pick something up or holding it to equip it instead of having to scroll through the menu for the option, the menu of which changes based on the object? Holding R to put it down again? Pressing E to pick something up HL2-style (same key as HL2, too) or holding the key to just use it? Having to hold E instead of scrolling down a menu again to find the proper option to access a container? The button press duration of which being entirely customizable in the options, specifically so you can avoid nearly all the 'QTE' issues you're apparently having? Having the option to drag large props with E or drag specific points by just pressing Shift and E? Not having to hit ALT to drop things — a modifier key that hasn't been commonly used by mainstream Steam games aside for 'alt-tabbing' purposes, for close to 20 years now?
And no, I haven't run into the problems you're using as examples, I'm sorry to say. If anything, any of the hurdles I did bump into would've been made worse with the old controls and lack of precise placement.
On the topic of anecdotal experiences, just about every other interaction has been made easier and a lot smoother for me — and the vast majority of players I've watched play the game recently. The only thing I'd agree with you about is not being able to pick up loose objects with a tool in hand is the tiniest bit inconvenient, something that I just assumed was a symptom of this being an entirely new control scheme in an experimental build.
If you want examples of my own; one of the games' main tasks—manning the terminal stations—has been made a lot easier and faster for me.
Total buttons needed: 2
No multi-button presses needed.
You can absolutely say you dislike it or that you have grievances with it, but that's literally more streamlined than before. Like, objectively. By definition.
And, you're right. The "nostalgia" and "afraid of change" comments aren't proper arguments, I'm sorry if that offended—but it does still ring pretty true. I haven't heard very many arguments here for the old controls being better other than just, "I preferred it" or "I was used to it".
Like I said in earlier comments, too. I would much prefer if the game gave players the option to either stick with the new controls or use the old ones. Aside from the work needed to implement it, there'd be literally no downsides to that, in my mind.
