The Spiked Titansteel Helm is being changed in patch 3.0.8.

The old, 3.0.3 version looks like this:

AP: str 113 => 259.9 AP (str x 2.3)
Crit: 66 => 1.27% crit (agi/52.08, it takes 52.08 agi to give you 1% crit)

The 3.0.8 version looks like this, (image courtesy of WorldOfRaids.com):

AP, JC pally:  97str+27str (from JC gem, see below) = 124str  => 285.2 AP (str x 2.3)
AP, non-JC pally:  97str+8str (from Soverign Twilight Opal) = 105str  => 241.5 AP (str x 2.3)
Crit: Crit Rating 52 => 1.13% crit

Overall effect of change (for JC pallys) = +25.3 AP, -0.10% Crit
Overall effect of change (for non-JC pallys) = -18.4 AP, -0.10% Crit

The nice part of the change is that there is now a blue socket in the helm. That will help my pally by freeing up the gem slot that I added with the Eternal Belt Buckle. Currently, I have a blue gem in there, the Perfect Sovereign Shadow Crystal. I will be able to move that gem from my belt buckle to the helm and replace it with either the Bold Scarlet Ruby (+16 str, blue quality gem) or the Perfect Bold Bloodstone (+14 str, green quality gem, perfect cut). Eventually, when my JC is high enough, I’ll probably just drop a Bold Dragons Eye (+27 str, prismatic) so that I can make the most of this helm.

This is going to be a major buff for my attack power but a slight nerf to crit rating.  Overall, I’m calling this a buff, for pallys who happen to be jewelcrafters and a nerf for non-JC pallys.
