From what I can tell:
Horde die less. Do a sort on deaths in the score card after a Horde victory (99% chance) and you’ll notice Horde die less than Alliance do.
Horde kill more. The corollary is that Horde get more killing blows than Alliance do.
Over and over. Horde players appear to be better and more skilled than Alliance. Maybe two years of raiding E-Z mode with Paladins has made them complacent.
I don’t know why.
Perhaps it’s the Alliance complainers seeking fast wins calling for “Let them just 5-cap so we can get fast badges.” Except, dude, that makes it just as fast for the Horde, and they get triple the badges. Which amounts to gear that bit more faster.
And don’t get me started on the Horde’s new AV habit of “back capping” towers nearly captured by the alliance and recoiling all the way back, through Frostwolf Graveyard, into Frostwolf Hold, harrassing the Alliance trying to kill Drek with all the Tower Masters up, all the while the Horde quietly kill Vann. It’s happening more and more.
It’s not a good season to be Alliance it seems.
