Why diss on sniper TSol?
He can shoot the snipers such as BW faster and get's a free reload with Marksman 
I don't really see the point to using it over the Saber, although to be fair I can't remember how many shielded mooks on Gold take more than one headshot to die with phasics. I used to use it a while back but it just never gave me the same desire to git gud as the saber did, although the saber has been my favourite gun ever since i first unlocked it in single player. I mean, I like gimp marksman setups like the spitfire, revenant, GPR, hell, even the katana, but something about BW Tsol fills me with a deep sense of "meh".
The biggest thing that pisses me off about it is all the reloading that you have to do while still in marksman mode. Free reloads for activating the power are cool but ARush seems more appropriate for that, and the ability to dodge as well as a stun power (frag nades) that isn't tied to the use of the free reload are much better for a sniper character.
