2 Big suggestions for the Game

1- Add the ability to create clans with your friends. Create a clan, add a name of your choice, customize the clan image, and tag. This way, you could host 4vs4 clan battle events and more content with your clan.

2- Add Warehouses, distribute some of them throughout the map, in different sizes. You can purchase them with coins. And once you own them, you can customize them. Change the decor, signs, colors, furniture, and add any ramp design you want, pools, pipes, etc. These warehouses will be instantiated, and you can invite people inside to skate. And you can create your own events in your own warehouse. You can allow access to members of your group, clan, etc. 

Just as ramps and items are unlocked for Builder Mode, these same items could be used to decorate warehouses. But since it's your own warehouse, all the ramps and configurations would be saved for you, forever. Until you decide to modify them. But it would also be nice to have ramps, pools, and larger items exclusive to warehouses. The unlocking system for these items could be the same as any other: completing map missions or participating in events. This gives you another reason to do these things.
