Yep, you are right, that is something you NEED when taking pics,
I own the 5dmkII and only the center is great, so I got a lot of manipulation to do to take a pic, maybe I'll wait for the 7D II or maybe a D600.....
I'll see
NEED? Really? I have a 7D, has many focus points. I mostly shoot sports, never use anything besides center focus point, or *sometimes* when positioned vertically the one to the right.
That said, photographers got by for a very very long time without anything but center. So you can argue the various pros and cons of other focus points, but you don't NEED anything besides the center point.
You can also spend 14+ hours on an internet messaging board arguing the minute points of focusing systems and build quality, or you know....get out and shoot
