Does anyone know if there's a LUA or addon or whatever to notify you of whenever there is an approaching Besieged and to keep you updated as to the progress of it? Basically, it will let you know whenever it is at Level 1, 2, 3, etc. and when they are advancing/attacking.
I can't imagine it would be hard to program/code a LUA to keep track of that sort of thing, but I have no idea where you would even start, or if one has already been made and is just not easily available on Windower.
