Well, considering things that need improvement...
I didn't have time to play 1.6, so I don't know how it looks now, but from earlier playthroughs I remember that whole Mandalore-Visas scene on Ravager (which starts with him activating the landmine) seamed VERY awkward to me. I find the placing of the scene totaly wrong and think that it should be removed all-together from TSLRCM, and put in new version of Ravager Rewrite that I think somebody mentioned that is been worked on, or Vpupets Malachor VI. It would fit in both much more than here, now.
First of all, what in a God's name is land mine doing on a command bridge?! How all the people who came to have auction with Nihilus before (Visas, Tobin and even Exile just few moments ago before fight) didn't activate it? Who put it there suddenly?! And why is now Visas giving encouraging to wounded Mandalore when they had absolutely no personal connections before? It just seamed to be put there artificially and out of content, and damaged the flow of scenes.
It is a nice scene though, and new camera looked fine, so it should not be tossed away but used in before mentioned mods because there they at least have spend some time alone, so it makes much more sense that way.
That's actually the only thing that I remember that needed improvement. All other things seamed totally fine to me.
