Maybe someone already said this, I'm not sure, but just because the Ramuh rings are i100, does not mean that they are not good. Actually, a few of the Ramuh rings are arguably best in slot compared to high allagan/soldiery rings. For instance, the judgement ring of healing is best in slow compared to the high allagan ring of healing for sch and arguably for whm based on spell speed values. The judgment ring of casting is also best in slot for smn and arguably blm if you don't require the acc from high allagan ring. It is a closer comparison for blm because blm relies more on spell speed then summoner does. High allagan ring of slaying has skill speed and acc, whereas the judgement ring of slaying has determination and crit rate. Again, depending on accuracy, the judgement ring of slaying pull ahead in pure dps just because of off stats.

TLDR: Do Ramuh, it is not pointless, and it is actually a very fun fight with cool music and mechanics
