She's right. It's kind of funny that way, because I'll hear "We suck! We always suck!" no matter what BG or what faction I'm running with. Since the Battlegroups were combined, I've seen little evidence of one faction's dominance over the BG scene. Sure, I've heard stories about how the Horde used to mop up BGs, but that isn't the case these days.
Some BGs are virtually identical for both factions --such as WSG or SoA or EotS-- but others do have a few critical differences. The choke point in AV close to the Horde base can be a deadly trap for the Alliance (I've been on the receiving end of that before), and the current strategies in IoC (Horde to Workshop and Ally to Docks) favors the Horde with the beefier demo units.
But that pales to how identical the BG chat is.
If there's one truism about pugging BGs in Cata, it's that the amount of time spent nerd raging in a BG is inversely proportional to the effect you have on a BG. If you're busy typing about how everyone blows chunks, you're probably not out fighting. Sure, you could have created a "We all suck!" macro, but most nerd ragers aren't satisfied with that simple --if inaccurate-- statement. Why stop with three words when twenty will do?
There's a special space in hell reserved for those people who need to channel their inner George S. Patton. "Get the EFC! Get the EFC!" says the toon who is jumping around back at the base. Meanwhile, five of his compatriots are busy attempting to chop their way through three healers and a Hunter to get at said EFC.
"We all suck! We were never good! Why did I ever FC to Ally anyway?"
Beats the hell outta me, man. If you were on the Horde side, you'd be saying the same thing in a losing effort.
If there's one problem I've had running BGs on both factions, it's the keeping track of what side I'm on.
You'd think that a (relatively) slim Blood Elf would stand out in contrast with a hulking male Draenei, but when I'm in the midst of a BG, keeping track of several things at once, I occasionally slip up and think I'm on the opposing faction. That can get unnerving in a constantly shifting BG such as Arathi Basin or Eye of the Storm, where you could end up running into the opposing faction's territory while you're examining the map. One minute you think you're rushing up to help defend a node, and the next you're back at the Spirit Healer.
Oh yeah... I think I need some coffee.
