FOA, if you're going deep enough to get CoH, I'm assuming you're healing at least T5 content.  If you're not, it's not worth it, and you need to completely reconsider the build.

Why are you doing Holy build and taking Spirit Tap?  If you're healing it is utterly useless.  Trade those 5 points for Mental Agility and you'll have a lot more mana longevity.

Further, Wand Specialization is another waste of talent points.  It's great for leveling, or if you are doing a ton of soloing, but useless if you're healing.  At least Unbreakable Will is situationally useful when healing; Wand Specialization is not even remotely useful.

Why AREN'T you grabbing Inspiration?  It is a very useful talent that saves ALL of your healers mana and can sometimes even prevent a wipe.  Instead, you're grabbing... Lightwell, Holy Nova, and an extra point in Holy Specialization?  Lightwell, is a waste.  Holy Nova is only situationally useful in 5-mans and PVP (and not useful at all if you're in content that would make you want CoH).  Holy Specialization is only useful IF you have Inspiration.

Finally, why are you even posting a CoH build in a LOLSmite thread?
