We fight on the flag because otherwise a lot of stuff becomes useless to us, and it is actually HARDER to target someone in the fray if they are with their group, someone could just look on the sidelines and see a white mage standing out in the open asking to be hit.
One of the ways to effectively capture the flag is to run in with the group and aura blast, you need 4 people to capture so its just better to pile in.
Why am I arguing with someone with what should really be (and from what I have observed is) a common strategy in frontlines...

Also I said calm down because your responses were getting aggressive and you were putting people down, so yeah... Take a breather calm down.
