Guild Wars 2

I read a lot of complains about zergs on the new world event in LA. People say that players just zerg all day and do not split up.

I think one of the causes is a lack of informative briefing before these events. People usually go for the most obvious and easiest. If no briefing was given, there is zero punishment for losing and zerging is the most rewarding style of play, then the players will go zerg each and everytime in these world events.

A simple mission briefing will really help the players in figuring out what to do and where they should go. It should include the following

-An overviewing map of the location
-Current situation, location of friendlies and foes, etc
-Objectives and where the players should be; where to defend or where to attack.

Take the Escape from LA for example:

-Map of the burning LA

-Orange circles indicating the spawn points of the refugees trying to escape.

-Then, orange circles indicating the poison gas machines that needs to be destroyed.

-Clear listing of the following 2 objectives:
1) Protect the refugees are they make their escape.
2) Destory the poison gas machines as they spawn, to delay the time of poison gas filling up the city. This gives you more time to save refugees.

-A clear listing of reward requirement:
Reward Determinant: The final reward is determined by how many refugees were saved in this run.
Rank A reward) 800 and above. This reward gives: XXXXXX
Rank B reward) Below 800. This reward gives: XXXXXX
Rank C reward) Below 400. This reward gives: XXXXXX
Rank D reward) Below 200. This reward gives: XXXXXX

Example of a simple yet effective briefing, which shows the players what they need to do to win.

I could have sworn there are scouts near the entrances that give such a overview when spoken to. But yeah, the rescue readout could have shown a rescued/needed rather than just the current rescued count.
