I'm planning to use new fire disintegrate rune with firebird+cindercoat+maximus and I have some questions.
1) Which Magic weapon rune to use?
- Force weapon +20% or Ignite?
Disintegrate seems to stack fire dmg pretty fast so I take Ignite is not so good?
2) Conflagration passive.
- Is it a mandatory passive for firebird builds?

thanks in advance
