Use proper English. 'u' and 'alot' are not words.
Joe Ego did a bit of work already on the subject at level 85, found here. Outside of base mana, nothing has really changed that would alter his work, so it should hold the same at 90. The main takeaways are:
- the viability of Glyph of Illumination is primarily dependent on Holy Shock usage (more frequent use of Shock = more mana gains), then on Critical %.
- at lower levels of spirit, Glyph of Illumination results in better mana regen; at higher levels of spirit, Spirit becomes better again
I quickly modified the spreadsheet for level 90 and it looks like in full 463 gear, with spirit food and flask, you should already be above the breakpoint where Spirit becomes better than the Glyph (assuming average usage e.g. ~9 Shocks-per-minute). It is probably not worth using the glyph until you have the T14-4pc and at least some heroic gear. If I can find some time this weekend, I'll try to put together a full set of heroic gear and see how the numbers compare (though I suspect it still won't be worth it, unless we end up with a significant amount of crit and/or low gains in spirit going from normal to heroic gear).
If anything I've written seems wrong, please don't hesitate to correct me.
Anything seems right and i thank u alot. x)
