To put it short: EVERYTHING in teh game just becomes a means to get a tiny bit of dilithium every day which you need huge amounts of to get anything for it.
It used to be, currency was the means to play the CONTENT!
It's totally backwards.
Cryptic does it like this to get you to log back in every day.
Get your Dilithium, get your dilithium...
Instead of Play our Content, play our Content...
That's why it's a grind and it becomes meaning less if that is ALL you do!
