In my opinion I feel like Guild Houses are pretty underwhelming when it comes to usefulness. Its pretty much just a forgettable cosmetic that COULD be much more interesting and have more interactive reasons for guildmates to actually go into them.
So why not have guild house exclusive warpers? A furniture that teleports people to certain predetermined areas when they touch them. (e.g. Swamp Fortress portal, Burger Refuge portal, MOD Fortress portal. Something that spawns them pretty close to the named location)
It could be great for organized raids and it would make the experience feel more action-packed and strategic when facing against enemy guilds, or just getting around the map for certain guild activities faster.
Not to mention you could sell furniture like this for a HECKTON of gralats due to how rad it would be. Imagine all those google play bux from buying portals and guild houses.
