Balancing for premades when forcing cross-faction BG
I understand the need of forcing cross-faction BG queueing, for example when a faction has less players queueing or the necessity to quickly finding players to fill up a team. The problem with this is that some BG maps are highly problematic (I'll explain why in a second), and forcing cross-faction means denying players of a means to avoid them, at least on some realms. In addition, those problematic BG maps have negative effects on participation and queue times, so some changes may be warranted.
For example, Alterac Valley:
There is a relatively small number of very skilled and organized players who pretty much farm AV whenever it starts, and are often able to graveyard camp the opposite team quickly, which makes the match pointless and truly a waste of time, I think everybody can honestly see that.
These players were previously playing Horde, and at some point they switched to Alliance. When they played Horde, Horde used to win AV. Since they switched to Alliance, Alliance usually wins AV. This is based on honest, direct experience.
Now, to be clear I don't really care about how those players spend their time, nor about how they play AV, but I don't think it's fair to force Alliance players, at least on Blackrock, to play on the side of Horde (forced cross-faction) against such premades, and it also has negative consequences (see the following comment).
It's worth noticing that Horde characters were previously not forced to cross-faction to Alliance when Horde used to win AV a lot. If anybody now finds himself against those premades, it would be fair to let them login their Alliance characters and not have to waste their time in there, when queueing for RBG. In fact it used to be like that, before cross-faction started being forced (for AV at least, and on Blackrock).
Proposed changes (alternative or combined):
1) stop forcing players into playing Horde against such Alliance premades/in AV, at least on Blackrock, would likely have favorable effects on participation and queue times.
2) detecting the number of premades (parties) and assigning a roughly equal number of premades/parties to the other side (or some other form of balancing) would make AV/IoC BG games not pointless, more balanced and thus more fun. In turn, this would increase RBG participation and decrease queue times.
Also if forced cross-faction is here to stay, I think it would be much more transparent to add a disclaimer to the "Opt-in to mercenary mode" settings, in order to communicate that it can be forced (on Blackrock at least).
Edit: I believe cross-faction isn't forced on Icecrown realm, so some things I said only apply to Blackrock, I updated the post to improve it and reflect that. I don't know about Lordaeron. This doesn't change the effects of the current situation, described in the following comments, and the (in my view) favorable effects some changes would have.
