As opposed to how difficult K1 was? Both KOTOR games could have used a difficulty upgrade, so I don't think it's accurate to label this as a K2 specific thing.
The entire story revolved around the main villains. Heck,
. You saw Sion twice before the final confrontation, plus all his cutscenes with Kreia. And Nihilus was seen around Visas' joining.
You knew that going in. Or atleast you should have since Obsidian made no bones about the fact they would be using the same engine and pretty much the same graphics. The engine can only make things look so good, since it's quite outdated nowadays.
Didn't really notice this one, so whatever.
You say you liked K1 more than K2, but yet you list this as one of your complaints? T3 was MUCH, MUCH better in K2 than he was in K1. For starters, he had a personality. You could actually have dialogue with him rather than in K1 where "T3 has nothing to say". I can't disagree more with this one.
MORE Force powers? They already have too many of them to begin with. As with graphics, the engine limits what they could make the Force powers appear to do. So what you're asking was an engine issue. Not to mention it was in K1.
Random loot generator. I rarely came across short lightsabers myself.
More than in K1
You mean like the Skybridge on Onderon? Not to mention it's a single player game. Having huge battles is better when it's multiplayer since as it is you can only control one person anyways so the rest would just be a big jumbled mess of NPCs fighting each other.
No comment.
