Actually getting the most use of it means you'd have to use it on cooldown every single cooldown and cast 10 spells, which can be hard without much of the healing being wasted/unnecessary
Eye hasn't really impressed me.
FoM has higher overall spirit than Tsunami assuming full uptime (as in it proccing every 60 seconds), but the 10% proc chance decreases that a bit. They are really about as good, but tsunami is more reliable.
Currently using Tsunami+FoM, will probably switch FoM for Jaws when i get it, mainly for the higher intelect (which also adds regen btw).
