Hey, I'd like to pose a question for all the DK's on the forum regarding the usage of ERW.
Simply put, which is better usage of ERW assuming you'll get to use it twice per fight regardless of how you consume it, either;
1) Using it during your initial opener once all your runes are consumed to put out more obliterates during pillar of frost and your pot,
2) Using it when you're completely out of resources to use and it's your only button you can press.
It's never been such a clear-cut matter for me, as if I use it during opener I naturally cap resources, but I put more damage out during all my cools, but if I use it when I'm dry I don't waste any resources from it.
