I mean come on Ruki is one of the most consistent vocalists in this scene if not the most, he can deliver live just the same as in studio record. His voice is really polished and he still can show emotions through his voice. I think people can blame him for the direction of the band but not for his singing. That's just my opinion tho.
Anyways I wanna know which vocalists are better than him by your standards, so please name a few!
I do understand what you're talking about. The album is more consistent compared to Dogma and there's more variety. But as people have already mentioned, it lacks standout songs(like Dogma, Deux, Ominous)
