Arenanet have said, for those who dont know:
"Removing Heroes from GvG and HA. This is something that many players have been asking for for a long time. We still want people to be able to participate in the action even if they can’t field a full team, so we will replace Heroes with a bunch of new Henchmen. We are currently working on the details, so we can’t give you a concrete timeline, but we do know that we want you to be involved. We’re looking for suggestions on the skills you want to see for those Henchmen, so start thinking about those skill bars! "
Yay? :) I think it will be shineh
