Something that is annoying is needing or wanting to do fractals, dungeons or temples and not being able to find a party. Your guildees may have different time zones or simply they don’t feel like doing them. What ends up happening is that you spend hours just shouting or watching the text box hopping for a group of people that want to do the same event.
A solution to this would be a party board where you could sign-up for a specific dungeon, fractal or temple. Once the party board is filled with the required number of players a notification would be sent to all of them informing that they have a full team.
The location of the party board would be well situated in the hero panel.
