With all due respect, because I know that this is not your decision...
This is the dumbest thing possible. We are so used to click in a specific area, and about 99% of beta players play in live servers where buttons are still in the same place... How many angry customers for "wrong" click do you (not you beta team, obviously) want to have? Yeah, I know, there's the confirmation button but this is not the point: why changing something that worked perfectly fine in order to broke something that was totally good?
