Which means those extra skills won't be useful to you, until you swap one of the skills for it. You may have many skills unlocked, but you can only use 7 & 7 at any given time.
So more SPs let you use more "specs" or "classes" anytime you want. But they don't really impact your efficiency at a particular spec, assuming you had unlocked all the skills you wanted for it.
