And here is another change we will be seeing in patch 1.18a.

"[dev1124] Hiding Main Hand Arm & Tool Graphics
* The following addition is planned for the /display text command in 1.18a, with further functionality scheduled for 1.19.
This feature is still in development, and therefore subject to change.

The gear slot main will be added.

/display main on – Display main hand arms and tools at all times.
/display main off – Hide main hand arms and tools while in passive mode.

Functionality

When set to off, the main hand arms and tools of all PCs in passive mode will be hidden.
/display settings made by you are visible on your computer only. For example, if your main hand display is set to off, your gear will still be visible to other players.
/display settings will reset upon logging out.

*For 1.19, we plan to enhance this feature to reflect your /display settings on all other player’s computers. Also, personal /display settings will be saved upon logging out."
