Broken/Useless BLU magic

[Damane]

I saw a BLU the other day spamming Temp. Upheaval on multiple mobs to 'aga' them... I wondered if that was efficient too.

P.S. Retinal Glare is the light one, I assume?

temp. upheaval has decent dmg, whisker does more, BUT temp. upheaval has such a low cast and recast time. So it works well for AoE burn.
