Fester or other skills that give aether stacks. I'm basically wondering how often I should be using fester and other skill to gain aether stacks so that I'm maximizing my dps but at the same time I'm not doing it too often so that I don't have my cooldowns up when I cast DWT. I'm also wondering if I'm saving DWT for certain situations so that it's not wasted, should I also be saving my festers and other skills that give aether stacks since I might be loosing the stacks by saving DWT.
