HoG is the only 31 Warlock talent that doesn't have a glyph associated with it. Would be nice if it had a Prime glyph that decreased its CD by 2s (would make refreshing Immo a lot easier) and/or a Major glyph that increased it's aura by 5 yards.
What do you guys think? If you like it, feel free to suggest it on the Beta forums if you have access.
