Thanks for letting us know what you were thinking for missions, Chase.
mission: the scouring + purge the alien (Purge the Scouring Alien!)
deployment: hammer & anvil (maybe)
6 objectives, placed by players (per scouring)
primary: the scouring (we can provide players with paper to keep track of objective values, highly suggested)
secondary: purge the alien (kill points)
special rules: see missions
While even numbers is better than odd numbers places, it's still not great. You'll find things like the gunline army putting all their objectives on the back line, while the more assaulty army can't.
I really would prefer that half or all of the objectives be static. Or not hammer and anvil. H&A is probably the worst deployment to let people place objectives on. I like H&A, generally, just not when people get to place.
IN Big guns and scouring, are killing Heavy or Fast, respectively, worth extra points? That would affect my list choices, a lot. That's why they make them worth a victory point in those missions, so you don't just load up on them.
Tertiary will be slay the warlord, linebreaker and first blood at 1, 2, and 3 points a piece.
Rotating through which ones are worth the most points?
