About Surge of Light

I have seen some points that have been brought up about Surge of Light. Currently this talent gives you a 6% (if you spend two points in it) for your Smite and Heal casts to allow you to cast Flash Heal instantly, without mana cost, and without a chance to critical.

Before 4.0.1 this talent gave you the ability to instantly cast a mana and crit free Flash Heal 50% of the time after you get a critical with any of your spells. This allowed for instant Flash Heals to proc very often. Which in turn allowed you to obtain 3 stacks of Serendipity very easily, which also made casting a faster Prayer of Healing (or Greater Heal) easier.

Now the proc chance is very low. And by very low I mean that if I were to cast 100 Heals in a row, Surge of Light would only pop up 6 times. In a night of raiding (in WotLK content) spells like Renew, Prayer of Mending, and Circle of Healing are the major spells that are used. So out of the total amount of heals you cast the chance to pop a Surge of Light is even lower. Making a lot of raiding holy priests (a lot better than me) find this talent to be very useless.

I personnaly specced into Surge of Light. I have been running a lot of heroics, since I stopped raiding, which means I have been using Heal more often, so it is more useful to me than the alternative (Tome of Light: reduces the cooldown of Holy Word spells). Having said that, I definitely think that the proc chance is too low. I like having talents that cause spells to pop up, but I like them because those procs actually happen. With Surge of Light, it rarely pops up. If they want to keep it from being OP, I would either let it take the form of the older version with a 25% instead of 50% chance, or allow it proc off of all spell casts at the same 6% as it is now.

Something to make it cool and useful. Right now it feels like one of those old Darkmoon trinkets, or one of those Vanilla legendaries with a cool put rare proc.
