I miss the old days when we had Alliance A, B and C go left, right, and middle respectively. This Zerging with your team stuff is boring. I feel the only reason this happens is that nobody can 1:1 very well without backup, it's faster to build Battle highs as a unit or confront battle highs as a unit (because battle high wasn't a thing back in the old way), but I think the biggest offender that causes the zerg is the Mount Speed Upgrades being forced into PvP maps. It used to take a while to travel across the map. I do blame Mount Speed as one of the big offenders for the giant zergs.
