Auto-Matching for Guild Battles
October 19, 2010 by Vulcan
We have released a package of fixes in regards to the guild battles. We have implemented a couple of fixes to prevent people from inserting links of guilds and refreshing the guild battle list correctly so hopefully there is a greater supply of guild battles for people to participate in.
Additionally, we have introduced auto-matching that will match up guilds who have opted in to the list and pair them up for guild battles.
Thank you for your patience in waiting for these changes.
