What's being traded is a boost to SMN's AoE abilities with Blizzard II. It requires the SMN to be in close range (like WHM's Holy), but much more powerful than the LOL-worthy Tri-Disaster. It seems that they're trying to make SMN (and ARC) be AoE kings, while BLMs are more Single Target DPSers.

AoE Kings? Summoners? Are we looking at the same game? Black Mages are the residential AoE kings, where as summoners are single target DPS focused. They were trying to give all casters an AoE move, but they nerfed it down and it's expensive as hell to cast as it currently stands. Now, outside limited (debatable) usage in t4 and fate parties, there's no other point to using this ability. Unnecessary nerf was unnecessary.
