And here goes Havoc:
1, 3, 4, 6, 8, 10, 11, 15, 19. Only 10 is non-100%.
For Havoc 16, note that I failed because of the time limit rather than lack of skills. I believe you'll need a totally different approach to get around the time issue, and I'm not seeing any other approaches available when you can't use blockers.
