Also, when I change the bet amount it slows the roll down compared to setting a bet amount and spamming roll. Am I being paranoid
Always been like that for me. It's always faster when you spam click, it's as if the animation goes a little longer than it should, and it becomes clickable before it would otherwise finish. And the roll doesn't appear until the animation has finished. (The spinning animation hat is)
Doesn't have anything to do with changing bet amount afaik
He's the reason I always chuck it in xD.
