You are just flat out wrong, and here is the math.
Damaging spell casts work on a 2 roll system
First roll - hit or miss/resist
Second roll - does the spell crit

AeusThe way WoW calculates crit rate is over ALL attacks. Crit rate is not based on hits only. In other words, if you have a 5% crit rate, that 5% chance includes misses.
A 1% increase in your crit chance does not equal a 1% increase in your damage output. This is because of the simple fact that a spell that does not hit cannot crit. If you have a 15% chance to crit but a 17% chance to miss, you will only crit with 12.45% of your shadow bolts, (15*0.83). Now add 1% crit: (16*0.83) = 13.28, or a .83% increase. Whereas 1% hit is basically a 1% linear increase in damage output.
Raid buffed, raid consumables (no world buffs): 602 spellpower
602 spellpower * 6/7 (shadowbolt spellpower coefficient) = +520.3 dmg
SB Rank 9 = (455+508)/2 = 481.5 avg dmg
481.5+520.3 = 1001.8 avg sb damage
Scenario 1k:
v1 base: 1000 shadowbolts (15% crit, 17% miss)
830 hits, 170 misses
830 * 0.1245 = 103.3 crits
(830 - 103.3) * 1001.8 = 728,008.0 (damage from non-crits)
(103.3 * 1001.8) * 2 = 206,971.9 (Ruin empowered crits)
Total damage = 934,979.9 damage
v2 +1%crit: 1000 shadowbolts (16% crit, 17% miss)
830 hits, 170 misses
830 * 0.1328 = 110.2 crits
(830 - 110.2) * 1001.8 = 721,095.6 (damage from non-crits)
(110.2 * 1001.8) *2 = 220,796.7 (Ruin empowered crits)
Total damage = 941,892.3
Diff = 6,912.4 = +0.74% damage increase
v3 +1%hit: 1000 shadowbolts (15% crit, 16% miss)
840 hits, 160 misses
840 * 0.1245 = 104.6 crits
(840 - 104.6) * 1001.8 = 736,723.7 (damage from non-crits)
(104.6 * 1001.8) * 2 = 209,576.6 (Ruin empowered crits)
Total Damage = 946,300.3 damage
Diff = 11,320.4 = 1.21% damage increase
You can argue until you are blue in the face Cousy, but math is math.

Its spread out over all casts, not just hits.

this is accurate
