Here's a question about SS vs Crit.

It takes 10 Spell Speed casts to overcast a Crit build right? Does that take into consideration a crit or 2, or 3? If I crit 3 times in 10 casts, that's still more DPS than a Spell Speeds overcast.

By overcast, I mean the point in which a Spell Speed set up casts an extra spell over the Crit build. (SS casting 10 spells in the time it takes a Crit to cast 9)

I can crit anywhere from 2 times to 5 times per ten fire + proc casts. That's surely greater than SS turreting yes?
