Infusion of Light -- now affects Flash of Light or Holy Light. Flash of Light is reduced to 0 cast time with 2 ranks, meaning that if you're running around and get a Holy Shock crit, you can also Flash without stopping.
Not so sure I like this new version much at all.
The old version or even the current version, gave us control on when the proc was used. Essentially you'd work in a Holy Shock when it was available and flash in between. Holy Shock crits would keep an Infusion buff active for emergencies allowing you to still heal with shocks and flashes while storing the buff.
The new version however does not allow the buff to be saved at all for when it is needed. If you get a critical hit with your shocks and then proceed to continue healing (as the target needs it) you will uncontrollably use the Infusion of Light proc. This puts you in a position far to often where you must keep healing to get the target alive or not heal in order not to waste the buff.
Also you end up with issues of superfluous haste (a similar issue pops up with JotP + Light's Grace) and GCD clipping.
What are your thoughts?
