Event gh-The event gh wouldn't be as useful since events got nerfed,and event guilds don't need an added advantage for events and they would be the ones primarily buying the event gh's. Secondly you can buy a gh with small rivers in it and build your own bush races. Idk if you can slide across Icey chairs,but they could make an icey furniture patch that you could buy and set up to do ice races.

Tower gh-Team fort falls into more of the tower guild practice room. I don't like the idea of challenge rooms. I like they idea of a practice tower flag room. However you could use a statue or a wanted poster then have somebody defend and somebody attack. The goal would be to try and get to the item and change it to there avatar image. you could get a small group of ppl together and have 1 group all look like noobs and the other all look like something else to signify the teams. you could use the same format for gh ctf event using 2 posters or 2 statues.

social gh-no need

Farming gh- anybody on the tag would be able to lock/unlock gralats they created themselves. Also the farm could have a special colored grass that would make the gralats worth 1 additional gralat each time 1 was spawned. so for green it would count as 2 gralats instead of 1 and for blue gralats it would be worth 6.
