I can totally see your point with all those advantages. Moreover, I agree with them. But all of you seem to be missing the most important part of my previous posts - if it was an option, and not a built in necessity, server admins would be able to choose whether they want or not to have 3rd person or 1st person on the server, not necessarly a fixed value for either 3rd person or 1st person. So basicly if you want to play on a pure "sim" server, you would join a server with 1st person forced on. And if you want to have a little fun running around in a 'mech, killing enemies and looking at all those other cool looking 'mechs, then you join a server with 3rd person as an option. It all comes down to having an option, not an option forced on all servers. It's nothing that has to be done for all of us, it's a matter of choice for players whether they want to play with 3rd or 1st person.
And to finish this off - the subject of "having fun" is touchy subject. Some prefer playing everything in 1st and that's the way they're having fun, while others prefer the 3rd person option. Without the second option, lot's of people are denied of "having fun".
I doubt the devs will change their minds just because of me, but I just wanted to show you (devs), that not everyone is happy with your decision concerning external views.
