Looking at the skill mods above it seems to me some of them are widely underutilized and could be sprinkled around on gear to improve itemization. For example Abjuration has the potential to be a niche defensive stat, and yet it exists on very little gear at all. A quick search of the wiki showed that the mod is present on only 8 items, of which only two come from raid level encounters (one at T6, one at T10).
I'm not saying we need rune bonuses on everything, but as an enchanter who runes a LOT, this seems like a cool bonus which could spice up a lot of loot tables and provide some potential swap setups without being totally overpowered.
Thoughts?
