on argent dawn there are no horde in war mode anymore. i can do my daily stuff in mechagon and Nazjatar without seeing a single horde most of the time. ( there are generally few players overall. i can do /who and see 10-20 alliance in Nazjatar sometimes etc. )
game feels dead in warmode. i do like the 25% loot bonus with no strings attached though, as silly as it all is.
but yeah, this whole warmode thing is a failure and only divides the player base into even more isolated shards.
I started bfa on an rp realm (Defias). I soon found that rp wm shards are usually too quiet, and forum said normals were more active. So I transferred to a normal realm pretty quick, and never regretted it. WM is so much better on normal wm shards.
