More important things are on the burner most likely.
On a side note, my character has urinated on these places:
Three guildhouses; all but one is dead now.
Harnquist's smithy when he was out drinking; he sold me shoddy falchions.
Kada-El tavern's upper bedrooms.
The petrified kran; he did not give my intoxicated character sufficient directions.
Into the Laanx Dungeon abyss.
Into the Death Realm abyss.
On the highest balcony of the Arena onto the stands below; while a tournament ensued.
Over various rooftops; onto roleplay's below.
In short, if bathrooms became implemented my character who shall not be named will have no need of them, unless to promote a guild of whizzers. You could say that he is dedicated to his craft of drunkenness and debauchery, I know I do.
