No but what reinforcements did is make the zerg the only way to play. Could AV be zerged in 1.12, sure, was it zerged every game, hardly. In 1.12 playing D and breaking the zerg is an actual viable strategy for both sides that can lead to winning, after reinforcements it wasn’t.
What happened because of reinforcements and the map vastly favoring forward horde defensive positions is that they were winning almost every game just by playing D and alliance simply stopped queuing. So the agreed upon strat became that both sides just zerg and see who wins.
