You can only learn 1 tinker of the 8 at level 70, unless gnome, in which case you can learn 3, as you have stated you have synapse - and if you have had no others i presume you're not a gnome either, so to get it, you'll have to re-level engineering all together.

I'm currently leveling a gnome mage. 3/8 chance at synapse/tazik == happy mage!
The fact that you think you need to take engineering to do well on a mage says a lot....
You could faceroll just as well without profs, gems, and enchants.
Twinks gonna twinks and haters gonna hate, end of story.
