Most of them are orphaned because they didnt seem interesting enough and to me that could potentialy influence the result alot. Would you continue on a map that was stopped thanks to those issues? We need to pick the best out of them to even let that contest have a chance.There's plenty of maps that have been orphaned in that forum section
Thats why i came with the idea to do just a restyle using maps that have proven to work. It would only require map authors willing to let their map suffer the edits
And maybe with that even allow gamemode changes so for example a map can go from A/D payload to CP based MvM (while in that case the map doesnt require a layout change usualy - or minor ones for balance).
