Activities as guild party games
That would be fun. In addition to the “to the death” WvW and PvP matches, just challenging another guild to team with the highest score on some of the HoT Races like Bugs in the Branches. Which I think they need to bring to basic Tyria, btw. How about GvG Games like Capture the Flag in some of the JPs like that pirate ship jumper I forget the name. Or on the Aetherblade ship. or herding animals back into their pen in less time than the other team. The doylaks in Lornar’s Pass or beetles in TD.
