Why is warmode bonus 20% for alliance again

Not that it really matters that much to me, but since day 1 I have almost never seen Horde outnumber Alliance anywhere in the world except when a hapless 3-5 man alliance party walks up on a raid allowed quest.

I have been WM since day 1, and I am always outnumbered wherever I go. I do get the occasional me vs. another solo wanderer. We have a good running duel and then go our own ways. Other than that it is always 10-20 times outnumbered trying to get to the Tortle or away from the flightmaster.

It feels like the sharding tech is not working…or maybe there are just a lot of 5 box’d horde gatherers in wm skewing things that badly…
