Spells: Cascade of hail Fail?

[Daldaen]

Rain nukes are stationary. If you cast at point A and mob moves to point B, the 2nd and 3rd waves will not hit.
Rain nukes are limited to 4 hits total. Either you can hit the same mobs 3 times, you can hit 2 mobs twice each, or you can hit 4 mobs once each.*
*You, the caster, are exempt from this. You will get hit with all 3 waves regardless of how many mobs you hit if you cast it ontop of yourself
Rain nukes never leveled to increase waves unless that was an addition in the last 6 months.

I'm guessing either the mob you cast it on moved out of range, or you were hoping the jail with hit 4 targets with all 3 waves. When in actuality they made rain nukes suck for multiple targets, and it is less efficient than targeted AE nukes for multiple targets.
