what I mean is adding a 4th spec to each class that takes equal elements (for example) from say a Jugg and sorc and makes an entirely new combat style. I think Jugg-Sorc and Mara-Sin would have the most synergy for mirror specs.

But the Tech classes would also have many cross class synergys as well.

I dunno...seems a good way to add something new without having to create a whole new class.
