I started with Ziz's TR build but I'm struggling a little bit with mana on my TR Raider. Am I wrong for thinking Devouring Diadem seems like a good helm for this build? specially one with res/life

POB: https://pastebin.com/BPatMbAY

Pros:

• Solves my mana problems

• No need to get -X mana cost rings anymore

• Helps me socket either Vitality for more life regen and survivability against bosses which the build lacks or Flesh and Stone for mapping survivability

• Occasional life/mana regen while mapping due to Feast of Flesh

• +1 level on my auras

Cons:

• Losing damage by not being able to roll hunter's Nearby Enemies have - to chaos res

• Some life/res/stats depending on the roll on the diadem

• Some ES which doesn't mean much because Acrobatics

So, is there something I'm missing? because Devouring Diadem seems like a fantastic helmet after all the mana nerfs this league
