After finishing the atlas with the build I can confirm, that Power Siphon totems is still amazing.

Thanks to Power Siphon now firing at multiple targets at once a secondary clearing setup using Kinetic Blast is obsolete.

That has the nice benefit of not needing a 4 link in the helmet gaining 50% all resistance for easier gearing.

The all damage can freeze tincture is an amazing substitution for the build. It opens the cold/chill mastery for more damage taken on chilled/frozen enemies too which is a nice addition.

Most T16 bosses are perma-frozen unless they get huge buffs from Affliction.

Because Barrage is not needed any more getting 50% shock on pinnacle bosses is no problem.

The new Power Siphon easily gets to crit cap which means 100% chance to freeze too. A new idea is adding a Lethal Pride where normally Healhy Mind is placed which opens the chance for a lot of double damage modifiers. The Healthy Mind can be placed near the Scion area for a lot of mana.

The build feels amazing and flys through T16 content. It is a really good lab farmer too thanks to Agnostic, high mana and not so much life it is basically immune to traps.

Sidenote regarding Power Siphon of Archmage:

In the version I am playing the default Power Siphon is way better than the Archmage version. That is because my version is not reserving a huge amount mana. Additonally a lot of lightning damage is added via Arcane Cloak and Mind of the Council. The default Power Siphon gem has 59% more effictiveness of added damage compared to the Archmage gem. To benefit fully from Power Siphon of Archmage a different build would be needed (fully reserving mana and life for auras going for energy shield, no Arcane Cloak. Because of the low crit chance on the Archmage gem Elemental Overload might be better than going for high crit)
