Hmm... While I am not necessarily for or against full voicing per se, I cannot help seeing two very big issues with the approach:
1) The famous "Wait wtf did I just say"-scenario. You select a option thinking "Yeah, this is probably it." and then your character spews out something *completely* different from what you imagined. Has happened to me soooo many times in SWTOR that I even lost count. X]
2) And - "ah yes, my dwarven fighter has the same voice actor as my dragonborn wizard!" Full voicing (as in, character dialogue choices being voiced as well) means limited options when it comes sheer amount of voice actors.
