had a bit of fun with dalmar around andruk yesterday and they are not bad at all even with a moving target
the ray apears to be a few feet wide not just a line as what i would have thought of as near missies also landed
there big draw back is the cool down but i surpose you just switch to bolts.

at this time i consider it more as a way of saying hello as i close to axe range

"If you can't hit a bolt or a L50 straight on, you're not going to hit a ray -- insta cast won't matter if your aim isn't true"

if your aim is true you get 7 hits in the time it takes to cast 1 bolt that is not a bad opening move and i would guess a good mount killer when being attacked

ps most of my rays have now made 25
