Even so, if people save their 50 code, they'll have to reobtain all of their gear / character progress if they want to test out the other talents if there is no respec system.
I just feel like, eventually, people are going to agree on an 'optimal' talent path, and everyone will be using the same specs. Making us unable to respec will discourage that.
It's like Diablo II, pre-spec era. If you wanted to make a fire sorc instead of a light sorc, you could.. you just had to put in the time of making a new character. I don't know, just an idea.
