Voiced PC is basically a huge negative in every single game I've ever played. The best voice for the PC is the one in the player's head that speaks up when they see things and think about them.
The only voice lines I think are accepted are combat noises and spell casting. Beyond that, the only words my character thinks or speaks is up to *me*.
Definitely agree about voiced pc being a negative, usually end up playing most games with sound off or just environmental sounds on because the voices are so annoying and do not match my character.
I don't really like combat noises and spell casting either though. Never understood why we have to screech spells at the top of our lungs when casting, pretty sure vocalising can be at any volume. Most combat noises I find to be immersion breaking as well, especially for stealthy characters. Non stealthy types I can accept a bit of noise from, although they often end up sounding constipated to me.
On the contrary ...
Class-specific barks are usualy recipe for disaster. :-/
Especialy with custom character ...
Agreed.
