I main a Templar healer with Inner Light on both bars, but I've recently come across a lot of threads stating that spell damage is generally better than spell crit. And someone told me the skill only adds about 5% increased healing (he showed me the math, but I find it hard to understand without a detailed explanation).
I'm just looking to find out if the skill is worth having for the increase to max magicka and spell crit, or if something like the 10% resource regen from Repentance might be a better skill to utilize in its place?
I'm also interested in suggestions for other skills that might be more useful than Inner Light (either Templar, world or weapon skills that would suit a healer well). And if you believe Inner Light is worth the double barred status, I'd like to hear your beliefs on the subject.
