Well, I don't care what YOU think about it. The list isn't based on how lucky one person is and another isn't. The fact that you even get one every six runs means that isn't more rare than something like an Ashveins or even a Parpua or Pretty Parasol, which are also rares, but are not as easily gotten in the respect they're actually RARE, not as useful. Do YOU get CERTAIN "rares" from CERTAIN enemies every 5-6 times you play an area? If so, they're not higher than a Tier 3, at best. At least Adoralphs is harder to get from the enemy that drops it that ISN'T a Mother enemy, and it's not able to rolled for ungodly high stats nor always come with the highest element level for its weapon type. <_<

As for the Rappy Souls, that's more or less player-based. Besides, I'm not gonna be the one who constantly restarts characters just to get Rappy Souls. The fact that Rappies themselves are rare enemies and the only way to get Rappy Souls is to beat Rappies, rare enemies, means that they're more rare than certain other things. The fact that they're from rare enemies alone made them Tier 2, but the fact that's the only thing keeping them from moving down is the reason they're not Tier 1.
