What happens if you remove mana?

EB and high regen is a very huge investment, even if you don't have to worry about mana anymore you'll have a lot less life and could have spent the regen passives/item mods on necessary life.

Blood magic itself isn't so bad because it limits aura use, but it does mean that mana management that would likely require nodes to cover is instead ignoreable. Same with managing accuracy and RT. Theres arguements against both as to whether losing auras/crits that would otherwise require investment to make use of anyway are a fair trade when its only 1 point spent on the keystones.

The truely easy way to avoid mana costs is to just use a mana leech gem however, as there's no need at all to worry about regen or potions if the mana cost of the skill is covered. Considering most builds only need use 1 main attack skill this doesn't mean any loss other than 1 socket.

I've currently got an EB build with max'd regen, capable of running arctic armour at all times. But I might have been smarter to have just put a mana leech gem on my main attack instead of investing all these points and gear into mana. Or better yet, have gone with blood magic and lost no survivability and have a much easier time handling regen. Before arctic armour was added my current character felt like a big mistake.
