AoE - Can WAR learn from WoW?

I got an email recently from CMK author of the http://www.scarytoenails.com/ blog, he wanted to know if I thought WoW’s latest changes to AoE could be the solution for WAR’s rampant AoE of doom. I have to say before I got the email I hadn’t heard about the AoE changes in WoW, but I think he just might be onto something…

Here's the exact text of the change:

”Area-of-Effect Damage Caps: We’ve redesigned the way area damage is capped when hitting many targets. Instead of a hard cap on total damage done, the game now caps the total damage done at a value equal
to the damage the spell would do if it hit 10 targets. In other words, if a spell does 1000 damage to each target, it would hit up to 10 targets for 1000 each, but with more than 10 targets, each target would take 1000 damage divided by the number of targets. 20 targets would be hit for 500 damage each in that example.”

Obviously those numbers are just an example, but you get the idea. Would it be enough? Unless the reduction in power is significant, when 10 Bright Wizards/Sorcerers turn on their PBAoE it’s still going to be instant death for everyone in range. Yet potentially I think it could work, with some clever number juggling it could certainly have a big positive impact on AoE in WAR.
