So I was thinking about a new glyph, I would never get to play with it but I'd still like to share the idea, it's a Frenzy glyph that causes any affected mobs to attack the mob closest to them, regardless of their previous allegiance. If a Frenzied mob has no attack, it will still run towards the nearest mob it can see. Could be upgraded with Reduced or Increased durations and if it's AoE by default then it's range could be modified by Amplify or Dampen

I think one of the add-ons has a charm glyph that would cause this kind of reaction in a crowd of mobs, especially if you used Linger.
Still, I like it as a tactical idea.
