Here are my initial thoughts on the new update.
I don't get VS anymore because it does less damage than JT. With reduced casting times, I'd rather keep using JT and put the points I would have put into JT into something else. Not to mention the fact that VS has a long CD and you need to put points into skills that aren't that useful in raids (JTM, Memorize, LoV). Similarly, I dislike JTM because JT casts relatively fast now, so I would rather put the points elsewhere.
Now that Wind Seal provides you with 4 procs instead of 2, you will be using Cold Bolt less, which means Cold Bolt will make a smaller contribution to your overall DPS. Because of this, I might leave Cold Bolt at Level 1.
You might want to max thunderstorm for the electrostatic buff. Use it before you cast JT/VS to do an additional 20% damage.
Assuming we can get the high crit rate sorcerers had before, I would get Meditatio, the heals you can do with it now are insane.
I haven't had a chance to test out different builds because the game is so screwed up right now and the scarecrows in PvE Arena fight back. God dam man..
