I would like a toggle in the options so I can turn it off.
Exactly! For people like me who think the dirty faces idea is a bad idea, give us the option to turn it off. We can already turn off helm visualizations. Why is that? Because we customers are trying to make an interesting looking character during character creation and don't want our pretty faces covered up, that's why.
Most every RPG has already done away with the need to lug around massive amounts of food and water, because the players didn't want that much realism.
This whole dirty faces idea is terrible. At least the people demanding weight be added to items, consumption of food and drink, and that armor and weapons need to be repaired, could claim they had a legitimate argument that without these games would be too easy. There is no such argument for dirtying up our faces. So this is obviously the idea of some big mucky-muck (BM). The rational people at this company are too afraid to upset BM with the truth - dirty faces is silly.. I'd rather we be able to wear hoods to hide our faces, then to see them always covered in mud.
Why oh why do any of us even bother trying to make an interesting looking character during character creation, if it was all going to be be terminally covered in mud?
