Need? No. Want? Probably.

Let's use words carefully here.

Do you need TTL? No, you don't. Almost nobody does. Flash was around — and being used effectively — long before TTL appeared. The question "Do I need TTL?" is a bit like the question "Do I need an automatic exposure mode like P, A or S?" or "Do I need autofocus?" The answer to all these questions is No, you don't need that.

Getting a little bit less abstract and more practical: You really don't need TTL. I disagree with those who say it's necessary for shooting active subjects. I use manual flash at weddings a lot, photographing people dancing. Has various advantages and works just fine.

David Hobby, proprietor of the famous (and excellent) strobist.com web site (devoted to flash, especially off-camera flash) is an advocate of manual flash settings for real shooting.

Okay, that said, you probably want TTL. It certainly makes things easier.

I think sybersitizen's reply in this thread  is right on the money.
