Shadowflare + Swiftcast

[jars]

you're also making swift cast on shadow flare out to be some important dps increase. it's a 16% decrease in cast time on 1/2 shadow flares which is our lowest potency spell, minus the cast animation time of swiftcast. you probably get more out of using it on ruin 1 when you're on the move since you care so much about mp

Well, since we're discrediting your arguments:

About using Swift cast on Ruin 1:
Ruin 1 has 80 potency at the cost of 79 MP. This is 1,01 potency/mp
Shadowflare has a total potency of 250 at the cost of 212 mp. This results in 1,18 potency/mp
It also takes 25 Ruins to match 8 shadowflares. You're more likely to swiftcast 8 shadowflares than swiftcasting 25 ruins as well
Add in the fact that it takes 62,50 seconds to cast 25 ruins while it takes 24 seconds to cast 8 shadowflares. Assuming you Swiftcast 8 of each, this results in 20s GCD for Shadowflare while Swiftcasting Ruins still remains at 62,50s combined GCD and casting time.

Checkmate.
