I'd be down with removing Redstone and Raincliff. Redstone is only high in "popularity" because there was a group back in FFN that would constantly vote it. It is one of my most hated maps, as I've shared with Colax, and yes the props can be entirely small and cheap. In short the map is a clusterfuck of random items, like a 4x large Warehouse. Raincliff is just a poorly made ph map.
Edit: Redstone is liked by noobs who enjoy hiding as micro items because the avg player can't find them. Requires little skill, imagination, or improving.
