I didn't click the "like" button on either of two first posts because there are no PROs/CONs...

My PRO/CON about voice chat.

PRO:
Make things go easier...

CON:
They can kick me out all they want if not using a mic.
They can put me on their blacklist if they believe that I am an anti-social person (I won't tell anyone who I am.)
I am a leader and my party members want to use a mic.
They won't leave me alone even if they are trying to voice in my ears.
Voice Mail <<<< STFU!!! >.<

If they bring voice chat in the game, I guess I better off soloing all the way up or quit the game. I don't care if I am Legacy... *sigh*
