It would be cool if they added a new chat feature were the leader, chapions and officers in a guild could discuss new things and and ideas.
They have a leadership chat on Portal Quest but never did on Dragonsoul, which Disney Heroes is based off of. Basically, most guilds or at least the higher ranked ones use a chat outside of the game (i.e. Discord, WeChat, LINE). For some guilds the outside chat is easier to communicate and show screenshots.
