The HTFU mentality isn't applied to DUST.
Dust is F2P console shooter, it needs a bigger market to make a profit so they have to cater to everyone.
They might say the HTFU mentality is applied to DUST, but evidence shows otherwise and if they do the game won't survive long.
Do you know what EVE is doing right now?
Improving the UI to give you as much useful information as possible.
Why?
Because information is the one thing you DON'T want to take from a player.

Due to CCP's encouragement and general cheering on of the 'infiltration' that happened to my corp and tritan industries, I'd say yes. CCP does want dust to have a HTFU mentality. Do I know what eve is doing? Yes, they are cleaning up the UI to remove bad stuff they implemented years ago before they thought eve was going to be successful. Atleast, that's the bit you think is relevant to this thread. It's not, as this is a brand new game and different genre but with a similar design philosophy.

At this point in the argument, you're delving into game theory and perfect information. If you think that FPS players in an FPS should have perfect information, you're wrong. Eve needs to be a bit closer to perfect information than dust does. Putting up colored indicators to do the job that a skilled player should be doing is dumbing down the game.

Your argument makes no sense.

You don't casually glance away from the primary focus of your screen to check your health on the off chance that maybe it's increasing this time when you look at it.

You SHOULD glance down at it when you see a hit indicator to show that you're taking incoming fire, if only to gauge whether to run or fight.

It makes sense to have the same indicator for incoming fire regardless of source, particularly when one of the core focal points of the game is a mode with friendly fire. Just like it makes sense to have some form of visual indicator when being actively healed so that you're advised to check your health and see how fast it's recovering so you know when to go back into the fray, and how much extra damage you'll be able to take while being healed.

+1. Advice for OP, if your shooting someone and you get hit from behind, keep shooting, don't turn around. You might as well try to take one down with you.

That's wrong if you know what you're doing.
If you know your surroundings you can still survive and get both kills.
Its situational, but if you know the map you can still win a fight even if the enemy flanked you.

Your right, it's situational. For instance, if you are lees than a foot away from a piece of cover that completely protects you from both sides and offers a means of escape on the other end. But usually you get flanked in a large open area with little or no cover.

If friendly fire doesn't do damage then don't give a damage indicator for friendly fire. It's that simple. If it's not effecting me in any way, then I don't need to know about it, so even if you change the color I still have useless information flashing on my screen. Just get rid of it.
Alternatively, we might lower our weapons when friendlies are blocking our line of fire as long as the animation is fast enough that it doesn't effect our shooting at legitimate targets.
