Spell Speed is moreso a blm stat and has always been. Smn in the past had some benefit but i never mained smn so idk.
Sadly i had switched my main to DNC when Shadow came out but now for Savage i am wanted as Red Mage, lol.
The gear this patch for once takes blm into consideration with lots of spell speed, but alas the crafted gear also has lots of ss which now i have way too much of on my Red Mage.
If you are not already i would recommend joining balance discord, lots of information and players from all levels could offer you advice.
