Also having this issue, it also tends to mute everyone on the odd occasion.. Noticed this last night while playing League of Legends (wondered why I was talking to myself).. It also forces the user to switch from UDP to TCP packets..
Only reason I brought premium was for the sole purpose of not paying full price for the upcoming expansions, didn't really care for the prioritised queue or "hint" videos etc.. (Though I did pre-order the Limited Edition) I don't particularly mind...
