I love Dromund Kaas. I love it for the varied environments and its general personality and how there are sidequests hidden in a stretch of jungle just outside of Kaas City that took me multiple Imperial playthroughs to finally discover, and I love it especially in comparison to Coruscant.
I mean, I’m deeply glad that I started TOR with a Sith character, because Korriban > Dromund Kaas is the best pair of starting planets: they’re not tricky to navigate (Ord Mantell, Hutta and Tython, I’m looking at you), they are actually interesting to explore (unlike Coruscant), and did I mention the fact that this is one of the few planets featuring more than one type of environment?
And have you checked out those stormy skies with the lightning and thunder?
I totally dig the contrast of gleaming cityscape, rugged jungle with rivers and caves and waterfalls, and ancient ruins populated by vengeful spirits and possessed victims.
