I mean, you're sort of forgetting the fact that the Unseeing Eye also has the absurd scaling DR thing on top. I can't see how the trinket isn't either going to be brokenly, absurdly good for us because we actually want the 1k haste unlike every other tank class or going to be completely useless because the weird DR thing is horribly undertuned. It's one of those trinkets where I have to wonder how many times they passed the crack pipe around the raid design office before they settled on its current iteration - likely in the same session as they decided on the legendary rings, I guess. It just screams "AYY LMAO BROKEN SHIT" either way - there's no way it's going to go live in a balanced, not-useless-or-OP state.
I mean at this point I just want to get my hands on it and test it because TBH it doesn't seem like good trinket design at all to me.
