I've been a big fan of Phoenix for some time, but the wording as always be a little weird, especially compared to fireball.
Phoenix:
A fiery phoenix rises at your location, striking nearby foes for 7...91 fire damage, and flies out to your target, exploding on impact. This explosion strikes for an additional 15...75 fire damage.
Fireball:
Target foe and all adjacent foes are struck for 7...91 fire damage.
The way fireball reads, it will obviously strike foes around your target for the damage, but so does Phoenix, although it doesn't quite read that way.
Is this a bug or just poor templating?

on the other hand i have been happily surrounded by charr and used phoenix on the one next to me for double AOE damage to the whole crowd
