I roll Alliance 99% of the time on my toons; have done so for years. Here is what I came up with:
1.) Bad players are bad, but the can (and do) improve with knowledge. Unlike other games, there is no ‘Proving Grounds’ in PVP to teach the fundamentals, so new players are just “thrown in there” to the wolves. Alliance gets the majority of new players, and since a player gets better through experience, there is a steep learning curve. Most just quit or transfer to the Horde. There really needs to be a training system scenario (like the Proving Grounds) in the game.
2.) After 0130 EST, the factions swap roles, and the Alliance is much more coordinated/stronger/decisive. Whereas, the Horde play…really, really bad. Alliance-level bad. This dynamic happens for a few reasons which I will not get into here. However (if possible), avoid playing at any time other than that.
3.) Long-term/professional players/streamers really don’t have a preference, usually. There are positives and negatives to both sides.
4.) The epics are skewed against the Alliance, its true, but they do keep making the same time-wasting/fundamental mistakes as always (taking the long way to go AROUND Balinda is my favorite); it is cultural to the Alliance at this point. Refer to above what I said about the blue getting newer players.
5.) Roll with premades, preferrably on voice for faster comms. Can’t be understated. and is actually essential in PVP. Can’t believe still that Blizz went all these years without a keybind communication system; one that announces to your teammates (like, HELP! for instance, when you are in trouble—and in your language). In a day where we play on multi-lingual servers, having an announcement AND a waypoint over you is critical to team coordination.
People think that the ancient Spartans were badasses; they were, but no more than any other Greek city-state citizen as an indiviual; what made them better than their peers was their unparalleled ability to move and fight as a TEAM: Hordies are no different, especially when they are alone. The reason why Horde seems to dominant? Its because they have made this little lesson in teamwork a part of their faction’s culture in PVP.
The downside to the Horde is their ability and willingness to zugzug to oblivion, caring only for a good team fight, but not really paying attention to the scoreboard/flags/orbs. Use that against them and win the game.
Hope that helps.
