Most fun class for me is the juggernaut. Played Inquisitor; the game felt like easy mode. All the gunners feel like they use nerf guns. Juggernaut is a challenge, and you have to use tons of skills to be good. Inquisitor can mash just one skill to kill everything. I don't like playing the easier-to-use classes :3
You're complaining that the gun using classes feel like they have nerf weapons while using a class with a lightsaber that has to hit an enemy like 30 times to kill them. Did you even get mortar volley/death from above? There is no more satisfying an ability to use in any MMO than that on.
