Edit: The problem with said "marking" is that it would reward players who already know the maps, and can head right to the weak spots; while punishing the players who are newer, and have to search for them. Its better to just have them on the mission wheel so that you can be lead to them by the arrow if need be.
True. The mission wheel would be a better idea.
But will most likely be sought after anyway.
It'd probably award big points, so that would be true.
