I don't really think it works that way, but I'll certainly play the mission and try it out. Just offering a suggestion to make that one less harsh for slower armies with squishier troops.
I appreciate all feedback. But it sounds like you are asking for a mission to help armies with slow, weak troops. I am afraid that armies like that are just bad.
I don't believe codexes are designed around being able to hold the same objective the whole game. That would favor immobile gunline armies that can blow you off yours while castling up on their own. This mission is unlike any book mission and I think it's a good idea to keep that in mind.
Someone could score points for 1 or 2 turns and contest or leaf-blower objectives for the rest and that's pretty much the game (and not every army is able to do this), which I think is a little silly. When I played this mission at Templecon in 2013 my game was over on turn 2 because I had no way to catch up on the victory points, and I feel like it's poor mission design when that can be the case.
That mission has generally gotten me the most positive comments both in 2012 and 2013. If you notice, this year I changed it and gave you an option on how to better keep up this year. Besides, it doesn't say anywhere that you need to keep the same unit on the same objective.... there are many cases where you wouldn't want to do that.
Also, please explain to me how a gunline blowing all your units away is somehow worse in that mission than any other?
Your comment also implies that GW designs codexs and book missions with each other in mind, which I find highly dubious.
Also, this is only one mission. Most lists are not good at all missions.
What list were you running last year?
EDIT: I will definitely consider fast attack/heavy support scoring in this mission.
