[What rifles do you prefer?]

its the looks, its ALWAYS the looks

 

Same here

[Lethality viable for leveling?]

Eh I am at it differently. You are correct, pre-30 before you get Cull leveling up Leathality is such a pain. Once you get Cull and HS things start going pretty smoothly. I am still in my mid 30s and my OP can breeze through most mobs and usually has no issues with elites. I mostly use Lokin and have no problem. Comparing to Concealment though I have no idea as I leveled up as a Medic and switch to Leathality once I hit 30. Try the two specs out and see which one is more for you.

[operative stealth nerf]

Not seeing it, but we can always spread word on every patch that we got stealth nerfed.

[Operative or sniper]

It's more personal preference than anything. Do you like range or melee? Do you want to heal or deal straight DPS? I myself couldn't decided so I rolled both, got them both around 30ish and still can't decided still. I love them both. So more than anything, do research. Search the forums and look at youtube videos.

 

Edit: BTW I myself am a solo player as well and both my classes can solo fairly good; my OP being a Medic and my Sniper being Lethality.

[Black Robe]

Whoa the goth! Black robes just match the sith, lord of darkness.

[Maximum Mod Slots]

So then, would a "perfect" lightsaber have 5 slots?

 

Color Crystal, Mod, Hilt, Enhancement, and Augment?

 

Also, what profession makes the augments?

 

Can get Augments from Slicing.
