So, a couple of my friends and I have been experimenting with the three player strategies from the schemes and strategies deck. One of these, Stop the Ritual, involves the defender placing a scheme marker in base contact with a 50mm objective marker. Then, at the end of turn the defender scores one point and removes all such markers.
In our game, a couple turns in, one of the attackers realized something. He could use Obey to force a significant model of the defender to interact and place a scheme marker close to, but not in contact with the objective marker - as scheme markers can't be placed within 4" with interact actions this one AP has now denied the defender all four strategy VP.
Now, while there are a few niche abilities that consume friendly scheme markers (or can get them on top of each other or move them - though these are also rare), a huge number of crews do not have anyway I can find to pick up a friendly marker dropped in the wrong place - whether or not they wanted it there.
Have I missed something? Is there some universal rule I missed that let's you get rid of your own markers? Or is this scenario just broken in this situation? I wouldn't blame anyone for that - good multi-player formats are notoriously hard to balance. In this case we would probably just house rule this - 1 AP for a 4-8 VP swing is too much - but we preferred to find out if there is something we missed.
