How about instead of removing the possibility of queueing as a group, you allow for:
A: two different kinds of queues, solo and group queue ( I know this has been suggested several times and I wonder why they don't change it to that in the first place...)
B: at least allow for up to two players to queue together
Please consider this, because ....even though I very much look forward to these changes finally I can prove my mettle against a random bunch I know that most of the ppl actively playing BGs are the ones teaming up with at least one partner. And have been teaming up, in order not to get too frustrated when fighting 4 man premades. I don't have access to the numbers you have, but I bet, allowing for up two 2 players to team up will be more beneficial for BGs than, as the interest in them remains high, while you take away too much power from premades. Whereas by allowing only solo queue you take away the incentive to play for many of those you have teamed up with a buddy in the past couple of years. And don't forget that this is a game mode best to be enjoyed together.
Just my opinion...what do you think?
