Being back on subject now, to further accentuate the point of this thread, only the people that go to the DA have posted here. The absence of the naysayers (with the exception of R105) is proof of their abject fear of having their egos smashed.
I have never been to the DA and if someone is playing and having fun in the main arena why should he/she go to the DA at once when invited? Who is more concerned about their ego: the one who keeps on having fun and playing in the MA or the one who gets shot down and invites another player to the DA to have a "proper fight"? I read about the F3 view in this thread and not so long ago there was a topic about people using diving from altitude to have more energy when they merge at an agreed altitude in the DA.
If DA is your thing please do invite people there with you, but don`t always expect them to say yes. I have a feeling that an open invitation is a lot more promising. What are the chances that if someone adresses you directly you are going to play someone else`s game with questionable fairness for awhile until someone`s bruised ego gets recovered?
