The biggest issue at hand are the Alliance Pre Mades.
Any remotely decent Alliance player uses Crossrealm pre mades.
It's pretty insane actually, if you play against a Pre Made, 80% of Alliance is Rank 8 or higher, if you play vs. a pug, there's barely anyone above Rank 5.
Horde has simply wisened up and learned that they need to take advantage of every game they play vs. non pug get the most honor out of it.
The only issue that Alliance pre mades have is getting too cocky.
Horde Pug groups sometimes even win vs. Alliance Pre Mades because their strat "Straight rush for Drek" is rather obvious and can be countered if people enough people use the recall trinket.
