How about Blindness/Deafness for a debuffing Hexcrafter? Bouncing or Persistent would make for a good use of metamagic with it. Yes, it allows a save. However, by the time you consider that a debuffing Hexcrafter will have more than average trouble with hitting with his attacks (focusing on Int means lower Str and you only have so much Arcane Accuracy or True Strike) you already have a chance of Shocking Grasp not working much either. The proper metamagic makes it much more likely to be effective.
A Bouncing Blind/Deaf with Wayang is level 2 and a Persistent one is level 3. I agree that it's better for your main combat spells to be lower level if possible, but the fact that it's a medium range spell that doesn't require an attack roll makes it a better option in certain builds imo.
