Apparently, there was a meta change that we never saw coming, and it may be worth checking out.
The Burning Shadowspirit Diamond (54 Intellect, +3% crit damage) is now critical effect meaning we don't have to sacrifice Intellect to get +crit.
Derevka's written up a little Flash Heal post over on TalesOfAPriest.com, so if you'd like to read the short article it's right here.
What're your thoughts? Worth swapping the Ember for (especially freeing up more Intellect from yellow gems)?
