4 of you said the same thing basically and I'm not quoting all of you. The angle that other people are already bad so why worry about blu is fallacious. Yes, sure, some idiot sam only spamming hakaze because he is an ice samurai is already a menace, but blu as it is currently being shown allows you to build your own loadout. You've got 49 skills and you pick 24 of them. If you don't immediately see how this is a massive problem for the average player then I don't know what to tell you. Yeah, there's nothing that will prevent some idiot being complete trash no matter what job they end up on. There's also a very large range of players who aren't complete abject failures but also ain't that great and it's these players here that go from being a mediocre dps on bard to why is this idiot in tank stance on blu (like every smn you've ever grouped with that kept titan egi out). Or why are they only doing a single target rotation (because their AoE skills are hard to get).

tl;dr the potential failure points of blu are much more ample and likely to trip up people who would be otherwise passable and focusing on the complete dregs of the playerbase as a counterpoint is spurious.
