After unlocking Raiju I actually do like it a lot, I bought the tomestone gear on NIN so I am sorta semi going in on it as a possible new main too ( still want to see what changes they implement to MNK and also possibly NIN too ).

The main problem I have really is that melee skills end Raiju.
It's not a huge problem but I do think it's annoying and especially right after I dinged it did screw with my head a bit.

I'll wait until I see more official openers too but I do feel like the opener feels very crammed.
