You do realize that for the longest time back in the original game it was considered that AV was Alliance dominated right? Because their defensive bridge chokepoint was way more effective than the Horde one.
I think it’s a testament to how much of an advantage the Alliance have without realizing it when premading AV and specific strategy executions led to such massive winrates. I think the reason for the Alliance issues in AV was more the massive amount of bots and afk players, not the map.
