I love the Argent Peacemaker. As an elemental gun, it's reliable for picking things down... When it actually hits something.
It may be my poor aim, but I seem to find that the bullets of an AP seem to go right through things at times. Things, ranging from blocks, to enemies. More so blocks, though. Am I the only one who finds the hitbox of an AP bullet to seem inconsistent? I'm seriously considering slinging my Valiance over my AP, especially for FSC. The hitbox of Valiance bullets seems more accurate to the size of the bullet, it blows up blocks more reliably to my findings, but it has a smaller clip and has less DPS.
Is the trade off worth picking Valiance over AP?
Valiance is useful to push zombies away from the reviving-rings of the totems.
Valiance is useful to push zombies away from you when they are using their fire breath.
Valiance is easier to kill beasts in Depth 27 2nd room.
Apart from that, I personally prefer AP over Valiance in FSC.
