I played alliance in retail Vanilla WoW and decided to roll Horde this time around to experience the Horde side of the story (plus it would be nice to be on a winning side more often for once). So I made a tauren shaman. Holy shit! Questing in the tauren starting area is the worst thing in the WORLD - it's fit for someone with a mount, not a level 4 newbie. The travel times are insane compared to, say, Northshire, Teldrassil, etc. So after playing a while, I felt like a fish out of water, then reading the forums, I discovered that there's a "faction imbalance". Plus I missed Westfall a lot. So I changed, I'm playing Alliance now. I can only imagine that most other "nostalgic" players such as myself would likely not want to switch from Alliance because they just don't feel "at home" in Horde. Besides, if I wanted the "easy way out", I'd be playing retail.
So, I'm just pointing out that "faction imbalance" was the final reason I needed to hear to switch back to Alliance, so maybe it will affect other players the same way too. I may just be hopeful

And as for you, Ticktock, if I wanted to play BGs for PvP, I'd play Destiny, Call of Duty, or a number of other games where PvP means teleporting to a map and playing what seems more like a "competative sport". I like WoW for its world PvP. No other game does it better than WoW, and that's what makes WoW what it is. Creating 2 factions who hate each other and making the players choose? Making each faction unable to understand the language of the other one? That's what created the competitive community in WoW. That's what made some guilds notorious, taking their reputations outside of WoW into forums and making them rivals with other guilds. That's what allowed for EPIC (though notably messed up on some level) events such as the bombing of the funeral in Winterspring.
