I've been following the build given in the "revisted paths" thread on the new player advice forums for the "font of healing". As per the build, I took the quicken spell feat at level 9. The only problem is, I don't know when to use it....
I used it once on an end fight, but I'm not sure when else it would be useful enough to justify the 10 extra SP cost. I imagine for raid healing it's on all the time, but how do I know when to turn it on otherwise?
