A placebo is a medication that makes no physical change on the system, only imaginary.
So that is also a totally invalid comparison to crew skills, which have a very clear, published, objective, known impact on gameplay. Thus by definition are not placebos.
You made it “simple” but still “wrong”
Once every 20 or 30 games
Crew skills make a difference multiple times per game. One specific one, like I said earlier, such as reload rate, might make a difference every 2-3 games. But that was just one example of one skill. There’s like 12 other relevant skills beyond that example…
What in game proof do you have regarding the results of Crew training
I already told you. Any time you are 0.2 seconds away from killing a guy and he shoots you, and the remaining reload rate on your crew would have removed 0.2 or more seconds from your reload if fully maxxed and aced, then you died entirely due to reload crew skills.
Any time you got killed by a guy because part of your tank was sticking out due to your transmission being broken, and you were 0.5s away from fixing it, but a maxxed out crew would have had 1.2s faster overall repair, then you died entirely due to repair crew skills.
Any time you are shot in the gunner and die a moment before the gunner is replaced even though you’re aiming at the guy already, but your agility isn’t maxxed out, you died entirely due to agility crew skills.
Any time you drive past a brief opening between buildings in an open top and get peppered briefly by 7.62mm machine guns, and can clearly watch your crew shifting step by step from yellow to orange to red, and they die right before you make it across the gap, but you don’t have vitality maxxed out, you died entirely due to vitality crew skill.
If I round a corner and come face to face with another tank and they outdraw when I have a Gold Star Maxed out crew me is it only because they have a Platinum Star crew?
If you give me a specific replay, I could tell you objectively. You can calculate your turret slew rate and theirs and measure the angle, and quite possibly yes you’d have won maybe if yours was aced. That one happens just as often (dying entirely due to traverse rate), but it’s less easy to observe on the fly than the above examples.
You would also be dying to things like keen vision, but it’s hard to notice in game, even though it of course happens, because you don’t know when you can’t see what you can’t see. it’s still getting you killed regularly, though.
