I have never “poked” anyone in this regard, and neither have a great many other posters on the topic. It is not abusive or trolling to point out that pvp is, by its nature, an aggressive form of play.
Nobody plays any pvp game outside of WoW expecting a peaceful adventure; you attack and you expect to be attacked. The issue with WoW is that due to a certain lack of design insight, the developers occasionally make poor racial design decisions that cause players to choose one faction in preference to the other. It’s human nature to like having a slight advantage (real or otherwise) and so you will often get these mad swings off an even balance to the point where your side is outnumbered.
BUT this only really matters on a pvp server. On a normal server faction balance has little effect because you can only be attacked if you choose to make yourself available for combat. So you can do your quests and raids and mat farming because normal servers are exactly that - world pvp is a minor part of the game and pvp only really comes into effect in certain situations (such as perhaps wanting to stop the other side getting the tag on a world boss) or in battlegrounds.
So saying that choosing to play on a pvp server is a player-choice issue is exactly true. Anyone who chose to play Alliance when there was a pretty good idea that Horde would be the more popular choice on that server, did so knowing they might have a rough time. I’ve never seen any realistic methods of controlling faction imbalance because, ultimately, its all about player choice, and I figure if Blizzard knew a way of doing it so that nobody was disadvantaged, they would have done so by now.
