Then again, the mana concern is a valid point. During Sunwell it was ridiculous. Druids and Priests were using heavy-duty spells while staying at better mana levels than the supposed durability-healers that were Paladins simply due to the high amount of regen from spirit.
So... simply because Blizzard is allowing so much mana regeneration for healers you really can't practically limit spells by mana cost since that'll only cause one of two situations: low-end content the spell is unusable due to cost or high-end content the spell is a no-brainer since it doesn't cost enough (and there's really no option for a golden balance, either)
No, I DO agree that glyphs could perceivably be better utilized. There are always going to be useless glyphs (some of which deserves deletion, btw), though, that's just how it's going to stay.
