If there is are going to be quest objective pointers on the map, just like the ones in Oblivion, Fallout 3 and Fallout: New Vegas, please, please make the pointers distinctive by objective. If the quest has several optional objective, make the pointers distinct from the main objective pointer. I really like the quest pointers concept, but I get frustrated when there are 4 pointers on the map, and no way to tell which objective it is pointing too, if you haven't played through the quest before. Especially is the objective is optional, and can be skipped. Maybe you can use color coding on the pointers for 1st, 2nd, 3rd etc...
Or make it so that every quest has a single objective, so that there is a single quest pointer displayed with no optional objectives to confuse map reading.
Or perhaps make it so that you can select and objective and isolate it's pointer from the other quest objectives.
Something to show which objective the pointer is pointing at, when there are multiple pointers on the map.
