I have 2 delta recruit characters and a main I made 5 years ago, 2 of which are level 54 (the third is only level 24), and have saved all my crates. I never opened them to choose any marks. I'm really confused about what marks are and how I use them. My characters are Federation with the Tier 6 Andromeda class cruiser. I know on other threads the answer always seems to be "well if you care about this get those..." well, I don't even know what there is to "care about" meaning I have no clue even what I am supposed to be doing at "at end game" so I have no clue about what gear to get, what ships to get, what missions to play.. so perhaps this question is best left to the experts who have the time to answer. ;-)
I just need help understanding what's out there and what marks are, how to use them, what I need as a Fed character going forward. Thanks!
