It is normally the case that the que time is far longer on the Alliance side. Both was damage. Different wings, but as a new group. And the queue for BGs are a lot lower than that, even when the there isn't enlistment bonus on Alliance, which hasn't happened for a while, it's 4-8mins depending on time of the day.
I do LFR fairly often, not a LFR hero, but love to raid, and the queue time for LFR on the Alliance side has skyrocketed since Legion. As horde it has stayed the same. It is an issue just as much as for Battlegrounds. I would say normally its 40 minutes vs 10 if we are generous, as damage. Healer and tank is quite lower, for both sides.
