Big Joe Guns, on the other hand, doesn't get Pierce...Methinks thou dost forgeteth attachments such as Augnmented Spin Barrels and Bowcaster Accelerators...
And all Pierce is, effectively, is a damage bonus in most cases. So what's the difference when you could have a Joe Gun using a heavy rifle doing minimum 16 damage a hit? And that's without going crazy and getting carried away...
I forgot about the augments, but again, I was also noting that these things are extra work.
If you were a new character with a lightsaber and someone else was playing a new character with a rifle, you'll notice that the damage output will probably heavily favor the lightsaber as it essentially ignores all soak.
Now, if you gave that rifleslinger a Disruptor Rifle, threw in a few mods to increase damage (many of which have setbacks) and pierce, then help them build their talent trees around the weapon, then yes, I will concede that the rifle is the way to go at the moment.
But once we start seeing some of the Jedi talent trees, determining how they get the defensive capabilities, and/or if we ever get a Duelist-type character (yes, FFG, I would love to see a Duelist Tree somewhere, even if it's Universal like I'm statting it up) or tweak the Marauder's melee ability into Lightsabers, then the glowstick is deadlier.
But again, we go back to the point I was making earlier: any weapon can be insanely deadly in the right hands. In this game, "the right hands" include skill ratings and talents, neither of which we have on hand to do this discussion justice.
Now, to the OPs original purpose for this discussion: I still say it's something to consider before just dropping into the game, as it will add more story elements (the Order 66 discussion and my comment on living up to the Jedi ways), possible ways around "closed doors," beastly damage potential from ignored soak in combat, and when combat starts, they will probably be the first one targetted as they are wielding a weapon that marks them as a sentient with a price on their head.
Just adding two more credits into the discussion here.
