So according to your logic, you're better off losing 5% crit from your own gear, and compensating it with a hunter pet?
You realise every % of crit becomes more valuable the closer you get to 100 right?
Going from 20 to 25% is a 5/80 improvement, which is actually 6.25% more crit than before. Going from 25 to 30 (the same 5%) will increase the chance by 5/75, which is actually 6.67% more crit than before. (Example, if you were at 90% and added the "same" 5% it would mean a 50% more crit chance increase). As far as shadow priests go, aiming relevant haste breakpoints will gimp you too much at this level, since gear with haste is limited.
Now that that's cleared up, running a crit build doesn't necessarily mean I'm going glass-cannon gimping all-out crit. There would be no sense in attaining 1-2 more crit rating vs 20 spellpower for example.
But thanks
the difference from your build vs a glass canon build -
devout hammer + witch finger ( 6 int enchant offhand) = 18 int , 49 spell power
dignified staff - 9 int , 48 spell power
both weapons have soul frost (not counting soulfrost)
on ur set up u lose out on 1 spell power and 9 intellect, which is 10 spell power
helm tattered dread mist 8 int
spellpower googles extreme 18 int - another 10 spell power loss
tattered chest - chest 8int
mech overalls - 11 int - 3 int gained
rings - dread pirate / y.boons - 4 int
charged gear of int - 18 intellect
herb / skinning - 0 int
alch / engneering - 8 + 10 (googles ) , 3 ( mech) = 21 int
Your devouring plague is your intellect x 13.1% spell power every 1 sec for 6 secs
Your mind blast is also spell power x %
Pvp power on your cloak increase % off your damage, another reason to stack intellect /spell power
hotshots + 2 int
acidic +2
another eye of the best +7
greater inscription of discipline +5 spell power
My build vs Your build is 68 intellect + 6 spell power = 74 spell power loss on your build
(wowhead wont give me the right exact numbers currently)
lastly you play in the 20-24 bracket vs f2p with bearly 2k health your non crits will 1 shot 70% of the bracket + you play a faceroll class.
