I think it was mentioned before that pallys are going to be given another healing spell to fit the small, medium, large design Blizzard wants.

In addition to that they are switching Flash of Light and Holy Light so Holy Light becomes our small heal (typically means a slightly lower amount of mana).

Why they're changing the names/fit of the spells is a little weird I don't think it really is changing anything that's currently happening.

Yeah, I'm sure in the end it won't really matter. They try to do a pretty good job of keeping most things generally the same. Will still be odd dropping a Holy Light for my weenie heal.

As of right now on the Beta, Holy Light costs something laughable like 300-400 mana, and still heals for 4-5k on my averagely geared Prot spec. I am sure this will be tweaked more down the line, but so far they are definitely making it look like they want Holy Light as the small-cost heal.

If i remember correctly, in the beta holy light is a low cost, long cast time (3s), heal while flash of light has a short cast time (1.5), a high mana cost and heals for about the same as a holy light.

But i might be wrong as i'm not actually in the beta.

Thats why we have Judgement of the Wise. Cast your judgments and your mana pool rarely ever dips below 50%. At least for me it doesn't. And i'm constantly spamming judgments, consecration, crusader strike, divine storm, and when getting art of war exorcism. Ret pally's are fun ^-^
