The stickies crit without FL4K, I didn't argue against torgue I argued against the AR being needed statement
its not the crit aspect that's important in FL4K's case, its how the 25% chance to shoot two projectiles combined to the 33% chance of not consuming ammo actually bring insanity to the table since the damage of projectiles get amped up depending of the amount of stickies on a target (which also are dealing their own damage)
Then of course you can add his ability and the crits on top of it and you know it gets magical. But there aren't the main deal in the torgue stacking
