Well, it is a rare ass drop though, so I don't really have an issue with it being brokener.
Same with Haidate for 2h jobs, they're omgwtfamazing now, 15 Acc? AND 5% Haste, hot damn!
Go down a step from Adaberk to Berk +1, the previous best alternative, and you notice a different thing.
Say you're a Drk, you've got Homam Feet, Legs, and Hands, Bomblet, PCC, Swift belt, Sniper +1 and a Rajas.
That's +43 Acc right there before factoring in anything else, on top of the 30ish Acc from the base Dex you gained, and now if you had no body piece on, you'd be hitting really high Acc.
Is the 18 Acc on a Berk+1 going to outweigh the 6 Str/12 Att by swapping to Are's body?
Not like you're going to swap out Homam feet for anything in the foreseeable future, hands are pretty freaking awesome too, and legs have multiple benefits, fast cast being nice for Drk too.
So then you stack in the Adaberk with all that Homam and you've got a bunch of "wasted" Accuracy, not like you'd change it, but I imagine dropping PCC/Bomblet/Sniper+1 for Str/Att would be beneficial in this situation.
