Thanks for the help but I think people are misunderstanding me on one specific case.

I have Manafication ready, but on something over a group of 3, so I scatter first, now people said thunder or aero correct? so if it procs, why wouldn't I do scatter > stone > scatter > thunder? (starting at 0/0)
This means I would be hard casting scatter, then insta cast stone to use the proc, insted of aero, since people made it clear hard casting stone is useless.
