I use some force powers and a single saber.
I only play DS.
I tried both KOTOR and KOTOR 2 as LS, and I felt like a dork both times, and never finished the beginning areas due to trying to be "nice".
I use DS powers. No buffers.
I prefer not to handicap my character in such a way that I can't use abilities/skills that are in the game. So I always focus on one style, be in flurry, power attack or critical strike (being my favorite).
True, it's to provide entertainment, but there are lots of people that don't find being unstoppable destruction to be all that fun. Which is why difficulty sliders are usually added. Sadly, even on hard, the game is still so easy it's boring.
Ok, this reminds me of the Morrowind uber-fans trying to defend Morrowind being an easy game. They also told people to handicap themselves to the point of having a shell of a character. It was a silly idea back then, and it's just as silly for this game.
Heaven forbid they use what the developers gave them to use.
By making the rest of the game pointless?
