Holy Insight, not Seal of Insight there is a massive difference.1) I don't understand why Glyph of Illumination is not good enough. It has been my tormenting ever since MoP was released. I've been using the glyph excessively to test its worth using and I just can't find the reasons why its not good enough. I am most likely missing something out of the equation I just don't know what. I've been looking at Skada reports for all boss fights and I can see that the mana gained from Glyph of Illumination is most certainly a lot higher than 10% of what is lost from Seal of Insight. In all the bosses I try to melee as much as I can. Without a doubt Seal is insanely strong and without that mana gained I wouldn't be able to cope but at the same time I still require and need more and I pressume the glyph of Illumiation from what I've been reading is a mana loss and I struggle to understand how. Obviously for fights like Jin'rokh the glyph is stronger but let that boss aside lets take examples of bosses that you can melee 80%+ of the time, still Glyph of Illumination seems to be stronger than then 10% loss
