I have just canceled my subscription. After leveling two crafters (cybertech and artificer) to a full 400 point skills and levelling both to L50 I have realized obtaining any endgame schematics (23-26 tier) is impossible or extremely hard. I really wanted to continue playing, but I am not willing to spend hours and hours in operations and flashpoints only to find out the stuff I will receive for commendations cannot be reverse engineered anyway.

Absolutely. I would like this as well. While I did not learned all at level 1, still the offer is way too large for me and most of them I am not using any more. Instead of deleting it would be enough to have ability to filter by level or rating (to hide items below certain rating or below certain level), which is probably a lot easier to implement. Currently it is possible to sort by rating or level, but not filter by it, filtering can be done only by rarity or type.
