He means the proc, View(). I have never heard of any limit to it. Infact, I used it in a proc for oview(25). Actually, I might of done orange(25) I forget.

I've been using a lot of view() for things and I've noticed that view only reaches a limit of 10 or 11. Is there any way to extend this? Or get around it?

view, hearers, and range are all capped at 1 tile past the world view setting. The only way to increase them is to increase the games view. If you need further you'll need to write the proc yourself.
