I don't mind voicechat but chatting is more relaxing to me while voicechat tires me out fairly quick. Mainly because of people with a lot of background noise and changing volumes. When I'm on voicechat, I prefer to listen rather than talk, but I'm like that irl too, unless I'm on a rant :P

For new content, voicechat is nice to be able to tell people what to do quickly, but otherwise you don't really need it. I'm glad YoshiP doesn't want to implement an ingame solution, else voicechat would become mandatory.
