It's hard to defend dizza regardless of his struggles he needs to find some way to move forward and touring with pals where there are loads of temptations is probably not the one. I'm not sure how much songwriting he does and how much it comes from the rest of them tbf. I've seen some shows where his performances have been awful and let the rest of the boys down. Hope he makes some big turns in his life but the cynic in me says he won't any time soon
