Aeyela:
For a Yoichi Rng, Fencer is just as useful as Rancor Collar. Namas is not TP modded, so you only get 5% crit. On that note, a Rng crit, while not as much of an improvement as a melee crit, is still 1.8125*normal damage, so Rancor is not "useless" as you say.
Also, the chance of getting 0 Recycle procs is 4.1%, so building a hit build for a 5-hit regardless of Recycle or not is silly and defeats the purpose of using the Relic+2 head in the first place.
AF3+2 body gets the snapshot boost preshot, but the Ratk boost is at the end of the shot, same with the str. Loki's is pretty weak for ranged attack when STP can be made up easily elsewhere.
