Arcane before 2-t5 and BT loots
 

Is Arcane spec viable for a raid which is starting Gruul?

If i take my Spellfire out of bank, resocket my +dam gems to +int gems, get Blade of Wizardry and swap Spellstrike helm for t4 helm with meta, can i expect to outdo 10/48/3 mages?

If not, will it change after i get TLC and Violet Eye trinks?

If still not, will it change in 2.3, when Evoc starts scaling with Int, rather than with Spi?

If still not, should i consider holding off the arc spec altogether until i get to SSC?

P.S: i know there is a thread which deals with arc mages, but it is focused on bleeding edge raiding, and does not really answer my question

No, you can read the other threads where this is all covered in great depth.

Don't be lazy.
