can't expect pp to read this entire post ... but i had kinda reworked my initial proposal.
-Let our shocks not only hit the focused target, but also 3 nearby additional targets. (8yards)
-OR Let us spread our shocks with a instant spell (10sec). Each time we use this spell, our flame shock is spread on 3 nearby targets. (8yards)
-OR Give our chain lighning a chance to spread our flame shock dot on 3 unaffected targets in a 10 yard range.
-Let us spread our shocks by using the fire nova spell. Each time we use fire nova, there's a 25% chance each flame-shock dot will be duplicated on a onaffected target. (range 8yards)
but really, this treat isn't about my suggestions, it's about your's ;-)
