I still suck at this game. lol Too much starship combat for me. Wish it was mostly away team stuff, I'd be playing it every day. But nooooo, I get stuck on a starship part and don't touch it for almost a year. lol
Try the Featured Episodes which Cryptic reruns right now. They still have space combat but are very ground intensive and have generally better stories than leveling content.
Otherwise check out Foundry missions. Some players focus a lot more on ground because it allows more diveser story telling than space.
