I'm all for realism. However this game is going to the masses and there are plenty of less hardcore players who will simply stop playing if they can't have the crutches that they've grown accustomed to.
Furthermore their is an abundance of servers that disable third person which removes your disadvantage. I never have a problem finding a large choice to choose from.
Third-person is an important thing to some players, and a bunch of Let's Players who helped the community expand.
Finally the suggestions section is probably more suitable for posts like this which are not bugs and are completely intended. However one of the best possible middle-grounds have already been met.
