How would you make RDM more complex?

We could use more area attacks than Scatter and Moulinet. How about new spells that work off of Enhanced Scatter? For example, let's say the next expansion raises the level cap to 80.

Level 72: Scattershot
Trait
Improves chance of acquiring Enhanced Scatter from casting Scatter to 50%.

Level 75: Verwater
Spell
MP Cost: equal to Impact
Potency: 150 water
Range: 25 yalms, hits target and all enemies within a 5-yalm radius of target
Requires Enhanced Scatter to be cast. All enemies hit take 30 potency water damage over time for 21 seconds. Grants 5 white mana. 25% chance of granting the caster Enhanced Scatter.

Level 78: Verblizzard
Spell
MP Cost: equal to Impact
Potency: 200 ice
Range: 25 yalms, hits target and all enemies within a 5-yalm radius of target
Requires Enhanced Scatter to be cast. All enemies other than the first two hit do 5% less damage for 10 seconds. Grants 5 black mana. 25% chance of granting the caster Enhanced Scatter.

But does this actually increase complexity in any way? Granted I'd need to know what Verblizzard's actual damage and effect on the first two targets are, but without significant situational variance this seems like more of the braindead categoricals (more a matter of bloat than options) scorned on the first page.
