I know for a fact that consecrate is exempt from the aoe cap rule.

[size=12][b]Area damage caps[/b][/size]
These have been put on to most Area of Effect spells as of patch 2.2.

[b]Mechanics[/b]
Each rank of each spell has a damage cap. Once this cap will be reached the spell does less damage to compensate so that it will not exceed its cap. The caps are not affected by gear or talents. So if you have good gear, you will reach the cap on (many) fewer mobs.

Apparently if mobs resist, the other mobs get more damage for that tick up to the cap. Also, crits seem to be able to exceed the cap for the mobs which are critted. (or maybe there is a crit cap also which just hasn't been reached)

[b]Example[/b]
Let's make a fictional AoE spell with a stated damage of 200 and an (unstated) cap of 2000.

1 mob = 200
2 mobs = 400
10 mobs = 2000
11 mobs = 2000
181.8 each.
Now add +1000 damage gear at 40% effect to damage (+400).

1 mob = 600
2 mobs = 1200
3 mobs = 1800
4 mobs = 2000
500 each.
11 mobs = 2000
181.8 each just like before

There is a nice list of empirical testing done on a forum post which I will try to find again. [url='http://www.wowwiki.com/Area_damage_caps#cite_note-0

Area damage caps All area effect damage effects will have 'area damage caps' in patch 2.2.0 which limit the number of targets which will be affected by any AoE effects. There are already spells, such as Arcane Explosion (AE), using these to a certain extent. In the case of AE, the damage decreases per mob, up until about 15 mobs being, at which point it holds at a certain amount of minimum damage.
