I sort of use it a little different than most, most save Swiftcast for raise, I do not, and usually I will need to wait for the CD to raise a person. IMO if the content in question is even remotely challenging if a person dies chances are the raise is a waste. If I added all the times I raised people and divided that by the number of people that survived long enough to lose weakness, I could assume that 5% of my raises result in the person recovering. So , I use swiftcast for stoneskin or more-so a method of creating a powerfull heal while moving or instant medicas.
