I agree with OP for the most part; His ideas add a much needed flair to the class, imho. I'll admit while they are vague, they did apply a sniper formula to the Gunslinger which to me, hardly makes any sense. I spend most of my time in groups sitting down in one spot for the entirety of the fight letting my 5-6 skill rotation fly. If there was a run and gun class to be had in TOR, shouldn't it be Gunslinger?
My biggest complain is in boss fights where I literally don't make a movement for 5-10 minutes. With that said, I do love the class, story, and the character himself but ultimately for gameplay purposes I probably will roll a shadow as my alt.
