Vengeance:
AV: 50/50
AB: 85% Horde
WSG: 95% Horde
EotS: 85% Horde

I'm in Reckoning, as well. I'd say Allies lose around 75% on non-AV battlegrounds. I'm in there a lot and it's pretty hard to get a win and complete the dailies.

It was to the point where we were losing almost all AV matches. However, during the last couple of days, it's been about 50/50. The battles have been a lot more balanced and fun for some reason.

I'm Alliance on Smolderthorn (Reckoning)

First of all, I find that who wins in my battlegroup is heavily dependent on two things:
1) When you do it
The later in the night, the more likely that the Alliance are going to win.
Weekends tend to be rather bad for the alliance.
Yet, if I switch around, much of the time, there is a battleground that alliance is winning at that moment.
2) What your gear level is
-On my main, I've done enough battlegrounds to get the season 2 or 3 non-arena pieces (ring, neck, belt, cuffs...).
-Currently, I go to battlegrounds on my pre-kara alt in an effort to get tanking gear.
In my experience, the worse the gear (both sides), the worse the alliance does. Games where it seems it matched high end players and I see several both sides in Season 3 arena gear, there is a higher percent of alliance wins.

AV
I still have won the majority of my AVs, but what used to be a generally guaranteed win is now a pretty unpredictable. Honestly, I'm glad the Alliance lose more, because it makes the games a lot more interesting.

WSG
The games take forever. Since it is only ten players, I don't think it's fair to say that I've noticed a serious dominance of the horde, but I've definitely lost the majority of PuGs.

AB/EotS
The majority of the time, the alliance lose. Like I said, though, sometimes I got 10+ games straight without a loss.

Shiabre-Terenas-Reckoning group-Alliance.

I play exclusively in PUGs, mainly during the daytime and late at night.

AV: We still win 75%+ of the time, but its *MUCH* closer than it was before. The terrain around the home bases is now a much bigger factor, and that terrain heavily favors the Horde.

EotS: We've lost 80%+ of the games I've seen.

WSG: We lose 80%+ of the games. No communication/teamwork means no chance at victory.

AB: When we target the Blacksmith first and hold it, we win 75% of the time. When nobody listens (which is the norm) we lose 95% of the time.

The downfall of the Alliance is the "hero complex". Everyone seems to believe they can be the hero, and thus ignores the team aspect of the game. This has much less of an effect on AV, where it is basically PvE with PvP to make it more interesting.

When it comes to queue times, I see no problem getting into a battle at almost any time day or night.

That's being generous. I'd say the Alliance win rate on Emberstorm is probably closer to 70-80% in AV. It just depends how many "NO D JUST ZERG VAN" players are on.

I swear they must have that macroed.

In the lower rungs, at least, Emberstorm is dominated by the Alliance. I've played in Warsong Gulch 10-20 as both sides, and Arathi Basin 20-29 as Horde, and in all cases the Alliance has been a near unstoppable force. Some of the most dominating victories... and crushing defeats... I've ever seen on any server have been here, with the Alliance demolishing the Horde.

i'm on malfurion horde (in shadowburn grp) and even though we have 45 min to 1 hr queues for AV, we win every time. in every other BG it's a miracle if horde wins in a pug.

im shadowburn alliance, and we generally lose AV because we cant push through 3 horde which are guarding IBgy. But in EotS and WSG we win like 60% of the time, i've grown to love WSG after just farming it a ton one weekend with a guild premade.AB is typically 50/50

overall our battlegroup isn't bad.

I'm Shadowburn Horde, specifically Sargeras, level 45. I've noticed that (at least 40-49 and below) it's pretty fairly matched. Horde seems a little better at AB, Allies better at WSG. Just wondering, are the allies protesting AV on Shadowburn? I can't go 20 seconds in a city without being overwhelmed with the posts about AV queue times in trade chat. Also, the 19 twinks ally side completely own. If I were to ever make a twink on this battlegroup, it wouldn't be 19, that's all I'm gonna say.

Horde(Kalecgos)

with my experience, we win about 90% AV's. All other bg's we lose about 80% of the time.
