I think players have the right to be concerned. Here's a video I could find from 2014:

I understand the need for shields in the game, also speed cap and other stuff which are needed for gameplay reasons. But weapons which regenerate shields when fired at friends doesn't really fall under "as scientifically accurate as we can make it".
I understand the intent to have a mechanic where players assist each other in combat. I agree it adds positively to the game. But it could be done differently than taking a weapon which was designed for destruction, giving it a green wavy fire effect and serving it to us on a platter.
PS: I think I'm right in saying that this thread isn't specifically about walking around and about the game turning into a korean mmo clone. It's just the OP's way of finding an over the top analogy between the most common gameplay elements today (third person view of a character). The point is that Elite : Dangerous has a certain flavor no other game has, and I personally would hate to see that lost.
