Hello, guys! I've done some tests with my blizzard sorceress and I was shocked:

9 cold skillers 45 life = 18k blizzard dmg / -270 enemy cold res
Sunder (14 cold skill dmg + 60 life + other adds) + 8 cold skillers 45 life = 19k blizzard dmg / -265 enemy cold res + higher life

The throwback of usng the sunder is having lowered cold resists which isn't much of a problem vs most of the opponents as they are not cold dmg.

Is using renewed sunders in PvP now the new meta? Are other sunders vital in PvP just like the cold one on blizzard sorc?
