In comments on the previous post GoW asked:
How do the cloak enhancement thingies factor in?
There are three:
Darkglow Embroidery – Requires tailoring 400 – Proc: Restore 300 mana when you cast a spell (35% proc rate, ~60-75s internal cooldown) (worth approximately 17 mp5) (only procs on spell -cast- not on dot tick)
Lightweave Embroidery – Requires tailoring 400 – Proc: 1000-1200 holy damage (50% proc rate, 45s internal cooldown) (worth approximately 24.4 dps) (only procs on spell -cast- not on dot tick)
Swordguard Embroidery – Requires tailoring 400 – Proc: 300 AP (25% proc rate with a 60 second internal cooldown)
The first and the last one are obvious no-gos for Warlocks. MP5 is for healers and Mages and AP is for melee.
So we’re left juggling a proc that gives holy damage to the tune of ~24.4 additional dps vs 23 haste. The comments on wowhead go back and forth on it. The take away seems to be “the difference is very slim”.
So, since Lightweave Embroidery and +23 haste are equivalent, Lightweave isn’t a good argument for why I should keep tailoring.
