You're not the only one, I went back to playing TOR again (after 6 months) because of Season 7's excessive grind already has burnt me out.
Omega Mark Grinding
Romulan Mark Grinding
Fleet Mark Grinding
Man this isn't a game we can enjoy anymore, its another job!
That's pretty light grinding considering a lot of those are balled into one. And you don't have to do all of those at once really.
As far as grinds go, STO is pretty light considering while you have to grind, you are also assured to get something after a number of attempts. Instead of being on your 1000th run of some dungeon hoping for that one item to drop you want to drop, and for you to get it (a bit of an exaggeration, but it can happen)
