If you’re ever thinking about PvP, I would get Earthquake instead of Energy Bolt because of the disrupt and you’re basically replacing Energy Bolt with Ice Bolt and Ice Pike AFAIK but that’s just my opinion since I’m not really into Energy Bolt without Linker and even then I think Earthquake (not sure if it still breaks the links or not) would be better.
Truthfully, I’m not so sure about Transpose as a skill unless you go Full CON or Full INT because with the attribute if I’m understanding it correctly, makes it so the average of your 2 stats will become the new stat when you’re buffed with Transpose.
I also think that you might have trouble overall with the DPS since you’d be relying on 2-4 skills but seeing as you’re trying to go for Tank/Support Wiz, that’s a great build because of CC Freeze of Cryomancer and the buffs are straight damage and defense.
My only gripe with your choice of Thaumaturge skills is Swell Body and Shrink Body. I think that you should switch the two skill points around since Swell Body just seems to make the enemy harder but gives more rewards so it sounds like a buff for the mob you’re “Debuffing”. Transpose also could use some love with more Skill points but that’s just my take on it.
