Without soaking, ERW or sitting on Runes then my Breath's are about 10-12 seconds spending Runes normally rather than trying to use FeS to buy extra time. Doing this as an Orc aswell so no racial help. 17+ seconds in an actual live raid environment is looking like a bit of an ask really. Gonna keep trying but with this sorta theorycrafting in mind, it ain't all that encouraging.
