Gauss in proper hands is IMBA gun.
Ok, maybe. It doesn't cost much APs to shoot with it. Haven't played with one.
I've played with 6 21-lvl chars. I tried to make the best non-BG char, but even the most powerful is weaker than my 200-hp-16AP-2-burst-BG.
2-eye shot sniper (sniper rifle, .223 pistol) has to little hps to live after 2 LSW bursts, one shot sniper with high EN will die anyway, cuz his one shot NEEDS to be a critical hit.
Crippler will probably have low sequence OR low hps OR low skill (possible to fight efficiently only in close range). BGs which have a lot of APs still have high EN and are fighting well on close and long range efficiently.
And I'm pretty sure you die (or enemy manages to escape) most of the times when you come into the BG's encouter (like camping in TB).
What I wanna say (but you don't listen, because you love owning with BGs or are "pretty happy" with other anti-BG builds) is that
2 bursts with LSW are more painful than 2 sniper shots. Cuz even with 25-35% crit chance they can be like only "30dmg hits" few times in a row (while burst is stable dmg at most times) and
you want to nerf it anyway.
My only hope is that AC/skill needed to hit will work for snipers (they, of course when having enough skill, should hit easier a target than burster does with his heavy weapon). That a burst vs. armored char will not be as deadly as it is now (cuz armor should prevent from taking dmg, right?).
