It's perfectly ok - you have nothing to worry about.
Those who have an "advantage" by being able to grind out engineer mods for hours are absolutely free to do so. It's all part of the game - and there are many juicy things to be found there.
However, those who spend their most precious resource of all attempting to perfect space ships in a space ship game may want to look outside once in a while. There's nothing wrong with it of course, I do it too. But there is a point when I can simply say "Sod it" and dump the game and take the GF out for dinner on the motorbike.
What confuses me is the mindset of some people who will actually say "Dump the GF and motorbike - git gud at the game!"
I've got a few motorbikes, and a sports car, but no girlfriend. I've tried, but my wife won't let me date anymore. I have a few psychological issues that prevent me from sleeping much, so I have time to grind out a bit.
