Further, the best reason for the glyph is that it allows you to regen mana during high healing intensity phases w/o spending a lot of globals. For example, I often have high mana and some amount (around five for example) mana tea stacks going into, say, empress P3 or protectors heroic boss 3. If it wasn't glyphed I'd be unable to really regen any mana during those phases (one global of ten is one thing, but a large set of globals mid-damage phase? not happening.) Since a lot of those high damage phases tend to be at the end of a fight, using the glyph means you would likely end a fight with a lot of stacks. As such, the glyph gains value since it lets you consume more stacks/at more times in the fight (using less globals, also being instant, it means you will continue to eminence heal while regenning mana.)
