I’ve expressed sympathy in numerous threads. I understand both why people are upset at its nerf, and why Blizzard chose to nerf it. I may have even made the chronologically earliest thread on the paladin forums saying I was sorry to see it go.
edit:
That said, I’m not convinced people will need to spam cast FoL. You can still talent for two infusions, and with the short cooldown of Holy Shock you are likely to often have at least one up, which will make your Flash instant. I think there will still be relatively VERY little standing and casting unless you want there to be.
