Use account names for guild chat?
Yes this would be helpful.
It the meantime you can hover and see their account name in tooltip.
But having the ability to either see account name or toon name (or both) would be great.

this can be expanded to all chat channels. A siple option for chat: [x] show account name will be easily to implement alongside all other options
Account names (similar to what we already see on the forums) are already displayed in the guild roster. So I can see if Random Alt A and Random Alt X are played by the same person just by comparing that name (which also shows at all times even when they are offline).
Make a note of the name next time that person is online in the guild. If you’re having trouble with remembering the connection write it down on a piece of paper and have it nearby. A notepad works wonders for when you need to jot down information like this for reference later.
If you are friended with them and you mouse over the toons name in chat, it will show you their account name. That might help.
