I hope its not just me that has noticed but when changing stances etc ingame, particulally when wielding a lightsaber, out comes the glowy blade or guns or whatever weapon you currently have equipped and there it stays until next time you leave combat, so for some we spend the next upto 20mins + depending if your running around the city, crafting or such, with a lightsaber in hand.
i know this is cool is some instances like when entering into pvp warzones etc, but it would be nice if there was a button you could push that could holster the weapon if you know your not going to be in combat for a while.
