I see where you are coming from, however, I disagree.  It is a good way of challenging yourself.  One can pick a goal, mark it, and have it listed at the top of their hanger right before heading into a match to remind them of that goal.  This then pushes them to achieve that goal and get better in one particular skill, weapon, or mech.

Out of curiosity, why is it that you wish for them to drop these various things?

Should be obvious gambling like mechanics are bad in a children's game. But it's also part of the fomo. It's the game demanding play time as opposed to earning it. Why can't they design other ways to encourage people to work on certain skills? And obviously pay to win is bad.
