What does the small shield above the Guild Battlegrounds indicate/mean? It is sometimes there on my page and sometimes not. Is it any advantage to open up the Battlegrounds area when this shield is there?
When you fight your first battle or negotiate and win, the shield will disappear. It will appear again when it reset (server time), and your attrition level is zero. This would be a good time to continue your GBG battles, until your attrition level is too high.
