Here is some very complex meta analysis math for you, since apparently you just really love that.
Agripinaa Braced Auto Gun
DPS: 2,266
Blessings: Easy access to large damage bonuses by just shooting and being close to enemies
Upsides: Very good ammo efficiency, good reload blessing makes reloading very fast if played right, extremely high stagger and suppression, good cleave make it able to mow down most mixed hoards. Practically a sniper rifle when combined with good dance of death use, otherwise wide spread makes suppression and hoard clear easier.
Downside: Poor accuracy unless combined with dance of death on zealot, slow reload without blessing use.
Recon Las MK 12
DPS: 1,460 (+ ~900)
Blessings: Extremely easy access to high crit chance and Infernus stacks that go up to +900dps
Upsides: Very fast reload resulting in essentially consistent dps, very good ammo total plus borderline overpowered synergy with shock trooper, infernus stacks stack very fast and kill even reapers from a fraction of a second of shooting them making the effective dps with optimal play insanely high, essentially doubled effect of all crits (1 crit = 2 crit shots) making infernus and shock trooper even better
Downside: Doesn’t cleave
Agripinaa Combat Shotgun
DPS: 1,058
Blessings: Conditional buffs that require very good ammo management and consistent play to benefit from.
Upsides: In very small cases considering optimized blessing and talent use it can deal damage almost as good as a plasma gun.
Downside: Poor ammo economy, very slow special shots, very bad reload management, bad accuracy, zero cleave.
The combat shotgun isnt complex, its just a worse braced auto gun.
Your saying that “um ackshually its not that bad because you see, in a very optimized case, considering perfect play, it can deal damage comparable to holding down M1 with BAG. So really its actually pretty good almost OP id say”
