I noticed there's theorycrafting going on here so I thought I could add in the guide I wrote a few months ago:

-----------------------------------------------------------------------------------------------------------------

How to calculate your CRIT value:

Your frost bolt does 456 avg dmg. (not the 446 its supposed to be, don't know why)

A solid preraid set of gear gives you spellpower of 400.

Full Raid consumes of +86 spellpower. (36 from Brilliant Wizard Oil and 35 Greater Arcane Elixir and 15 Elixir of Frost Power)

Frostbolt's spellpower coefficient is .814 (3/3.5 = .857 then .857*.95 = .814)

3/3.5 = cast time

5% reduction is because it has a slowing effect.

A few things we can ignore since we're trying to find equal values between crit and spellpower.

456 + (.814 coefficient * 486) = 852 dmg per frostbolt.

1% crit would over a long average be equal to 1% more damage per frost bolt. 852*.01 = 8.52 dmg.

8.52 / (spell coefficent = .814) = 10.46 Spellpower.

At this gear level 10.46 spellpower would be equal to 1% crit, and that would be the ratio you tradeoff your items for max theoretical DPS.

Now lets say you have better gear at a level of 450 Spellpower. +86 from Raid consumables.

1% crit = 10.96 SP

-----------------------------------------------------------------------------------------------------

How to value HIT:

You can't go above 16% hit (you get 6% from talents)

For spells, it is a 2 table roll. First the server rolls to see if you hit, then if you successfully landed your spell; it checks if you made a crit.

So 1 hit again, like crit adds 1% more damage per frostbolt in the long average, however this hit can cause a crit.

So a hit that would of missed, but this 1% hit changed it into successfully landing, this successful hit may now crit. So we need to take crit chance into calculation.

So 1 hit = [1% dmg of your frost bolt * your crit chance (5% base ~5% from gear 3% talents 10% WC = 23%)] / spell coefficient (.814)

OR 1 hit = [SP value of crit] * crit chance.

Gear: 400 SP +86 (from consumables) = 486.

852 dmg per frostbolt.

[8.52/.814 = 10.46] * 1.23 = 12.86 SP

At this gear level 12.86 spellpower would be equal to 1% hit, and that would be the ratio you tradeoff your items for max theoretical DPS.

Spellpower level: 450+86 = 536 SP

1% hit = 13.48 SP

The more spellpower you have, the more each crit and hit is worth.

--------------------------------------------------------------------------------------------------------

So you make tradeoffs on your items until you find your max DPS combination. If you want an item that is +15 sp OR 1% crit? You go with the 15 sp.

You want 8 sp OR 1 % hit? You go with the 1% hit.

Good luck!

I'm a huge theorycrafter so I was pretty excited by all this and looked through everything in this post

Now to look at some points i've seen through the thread:

Average frostbolt damage is 456. Not the 446 it is supposed to be - something server side they will fix eventually I'd guess. (Theorycraft says 486 but that is wrong)

Frostbolt coefficient is indeed ~.814

Looking through sumail's post I see that he varies his

crit and

hit ratio depending on how much he already has? For example .84/.83 (1%

vs 0%

hit) and .99/.98 ( 16

vs 15

hit), same for

crit. When looking at equivalencies it doesn't work like that, you aren't looking to see by how much % it improves by, but by absolute #'s. A 1%

hit increase from 1->2 is the same as 15->16. Getting more and more

crit or

hit shouldn't devalue the next one.

You put alot of work into it and took me a while to go through it (thankfully you put in end equations so I was able to skip some parts I didn't understand) I actually was able to fix one of my guide's problems by looking through yours

Edit: Thanks guys for the explanations! I'll be looking to fixup my stuff.
