Yes, so if you sit and just fire at someone enough, the damage stops being ignored and get redirected to your hull.
Actually turning pink is something that would require an active amount of team-damage'ing that you'd have to go out of your way to actually achieve.
While some folks do bring things like this up, players not griefing other players is still a very big positive. Sacrificing a bit of realism for a healthier game environment is a trade that has to happen sometimes.
I've heard this said repeatedly, but I've never heard why anyone would actually have come up with this idea.
Can you tell me why anyone would think this?
