User Macro and AFK BubbleUser Macro
There are a number of mmorpg that have this feature, which seems like an old feature. A feature I do not understand was not part of the standard features implemented to begin with with Champions Online in the first place.

Macro's allow you to combine multiple actions onto a single button.
However for the role-play community, we can for example use a macro to be assigned to an emote.
AFK Bubble
There is a feature that Chempions Online can easily add to the game. It might not seem to have much significance to the function of the game. However, I believe the role-player community would appreciate this feature.
A comic book thought bubble for player character to activate when a player goes AFK. This feature could be a good thing for the pve player to see that someone is afk.
For the role-player this feature combined with Key Bind and simple code would offer a good RP tool for a better RP experience. How the AFK Bubble message edited assists RP is to provide turn based rp. Meaning, for example 3 role-players wanting to post an rp post, whoever's Bubble comes up first goes first, etc.
So for example role-player; A, B, C. And B bubble is first seen, C is next, and A last. Which now means, B player types his or her rp post, then B, and ending with A. And after A, let's say that A bubble is seen first, then we see player C, and B last. Then we repeat the sequence for the turn based RP.
Often the player that has fast typing skills combined with a fast thought process can maintain the focus for an RP with others; and the slower player has fewer opportunities to participate.
For the Champions Online developers I have provided this code to consider to add CO.
Simple Key Bind code:
/bind enter "afk Typing...$$startchat"
/bind / "afk Slashing...$$beginchat /"
/bind numpadenter "afk OOCing...$$beginchat OOC: "
/bind ; "afk Emoting...$$beginchat ;"
/bind backspace "afk Sending a tell...$$autoreply"
