I run into this same mission at battlegrounds a couple times now (objective on their side worth 8, on your worth 2). The problem with that mission, specifically, is that some armies are just really hard to shift (MEQs, necrons).
I had basically the same sequence of events happen every time I've played that mission. Hell, Will and were really only 1 turn away from tabling them and we still only walked away with 7 pts. I personally have a visceral hatred for that mission.
But, obviously, it's not about me, the real problem is that you can have 2 losers walk away from that round. To Keith's pt, two good players play in turn 2, tie out, get 15 pts each. Turn 1 though, they get zero pts each.
I think in fact, if you love that type of scoring so much (I really don't) it would be much less bad if you had every round be like that.
The problem generall, btw, with non-zero sum scoring (like the 'ard boyz) is that it really rewards good players for getting a "puppy" to fight one round. Basically the winner of the tournament tends to be more heavily influnced by who got the easiest opponents so they could get full, max pts. Now of course, random matchups always affect the tournments a great deal anyway, but non zero-sum exacerbates it.
