As long as it's not a ton of spell speed I won't care much.

Though it if doesn't have a ton of spell speed, unless fights get much longer, there's not much reason to have more PIE (a WHM viewpoint at least). With the extra ilvl you can probably squeeze the pie needed into like two fewer pieces of gear that could then be Det/Crit. Wouldn't that be lovely?

Or, I suppose damage could be so much higher you have to use CureII a lot more even with the mind/det you get. But then you need a whole boatload more pie that probably wouldn't happen.
