Using the item comparison Theck
linked,
Valour's armory (first player in thread in Prot gear) and Rhidach's CTC calculator I get 1.54% block from int cloak vs 0.99% avoidance from str cloak. 0.55% CTC difference, which is 44 Mastery.
From Theck's MATLAB thread, the str cloak is worth ~290 DPS more. More DPS is always welcome.
If you want more DPS, go for the str Valor cloak
If you want more avoidance go for the str Valor cloak
If you want more sta go for agi Rhyolith cloak
If you want full CTC and have to use the int cloak which amounts to 44 Mastery worth of CTC - something is wrong.
Whoops. I took parry into account, but I made a mistake at the end. Here was my napkin math. After gemming/reforging like I did in the comparison, the Int cape gives you:
+123 mastery
-260xparry rating (250 base, 186*0.27*1.05*1.05=55 from strength)
-77 expertise (ignored)
+100 hit (ignored)
Using the rule of thumb that mastery is ~3x as effective as avoidance at CTC at reasonable levels of DR. That would mean that the extra mastery is worth ~123*3=369 parry rating for CTC purposes, giving the cloak a lead of ~109 parry rating.
Which I then divided by 179 and multiplied by 2.25 to convert into CTC percent to get 1.37%. Except that parry rating is 1%, not 2.25%. Oops. Fix that error, and it drops to around 0.61% CTC difference, which is an over-estimate due to DR on both ends (it's likely to be a higher ratio than 3:1 now, but the DR will also drop the effective CTC by 30-40% since we don't get the full 1% dodge from it).
Obviously I should have down-converted the parry to mastery, instead; that gives me (260/3)=87 effective mastery, 123-87=36 mastery differential, 36/179*2.25=0.45% CTC difference, right in line with Rhidach's spreadsheet.
Moral of the story: don't do napkin math while you're distracted by lab work.
