For SNS wizards, I'm assuming the following formula governs the critical procs with Wicked Wind: crit per second = [number of energy twisters out at full windup]*[tick rate/second]*proc_coef*crit_chance. Now while that sounds good, it seems like the standards SNS wizard (2.73aps/50cc) is only procing 4 crits per second at full wind up:
#of Energy Twisters at full windup = [(2.73-.95)*6] = 10.68
Proc Coefficient = 0.125;
Ticks Rate = 6 per second (for 2.73aps)
Crit Chance = 50%
Critical Procs: 10.68*6*0.125*.5 = 4.0050 crits per second
Doesn't 4 crits seem very low? I'm pretty darn sure we can reduce the cooldowns of spells a lot faster than that. At least by twice that much.
