The one good thing about the chat system is that alt 1-5 control which channel you're speaking in. It's a bit of an adjustment from having to type /t a_skeleton_03, /guild, /party, /say, before your messages but once you adjust it's much better.
The bad part is that there's no /invite a_skeleton_03. You have to have them respond to you, click their name and invite, or run up to them and hit ctrl -> f1 as quickly as you can before they run away.
the chat issues are compounded by the fact that if you're grinding you need to be constantly moving or a mob will spawn and kill you very quickly.
