Guys, I do not want to be rude, I like detailed suggestions (images, descriptions, pros and cons) but you should focus on other contriubution, transfer all energy to making custom and freshy maps would be a much better ihmo.
We got information that devs want to have maps, new suggestions when we do not know exactly what will be "after wipe" and how is real progress are pointless at the moment. In that case, new weapon might ruin planned things and probably slower the development process. I know it is easier add new weapon than make complete good-looking map, its time-consuming so it all means more contributors are welcome.
Just in case, run this tool several times, try something, ask on forum. Even simple unique random encs are nice addition to variety
