I never got too far into it to feel like it got really grindy. I think the farthest I've gotten in it was around the end of the Romulan episode on the Federation side, and I didn't get very far at all on the Klingon side. The beginning of the Romulan story is pretty fun I thought, and so far the game is fun and not grindy. Then again, my highest level character right now is level 8 so I can't much speak beyond the early game. I'm having a good time anyway. And as far as new stuff goes, beyond the extra bonuses from being a Delta Recruit, I haven't noticed too much changed. At least from the last time I played, the new Federation tutorial is nice, and maybe the Klingon one changed as well (not entirely sure though), and the Romulan tutorial was completely new to me since I never played Legacy of Romulus before.
