I dont think he's worse or even getting worse every tour...no...
but I do think that if he only focused on his playing, as his only job, he would play even better.
He doesnt add anything "new" to the solos nowadays...maybe since the 90s...I dont know.

He should leave this stupid clothing thing and focus only in music...

Only if he's sick of it already...who knows. Maybe he doesnt want to improve anymore, he thinks he's good the way he is now. Which I think he IS, of course..Im not saying he's not.
But an improvement is always good.
