You can always just run out of the giant red cone for Evil Eye. Don't need to stun/silence it, and it's especially hard for WAR since DRGs will likely be using their stun on cooldown and we have no silence ability. For Chaos Breath I just time a Vengeance, then when I'm rocked I pop Thrill + Convalescence. Haven't found a way to avoid it, LoSing would be super risky and would just cause too much chaos (eheheheh). Honestly, even if you can avoid it, it's like avoiding 2x WW in Garuda EX. Just take it to the face and you won't end up causing everyone's death in the process. Try to communicate with the healers once you've gotten the icon that you'll need big heals soon, mitigate afterward and you should be fine.
