New Wall Tech
Worker Path only has made some interesting changes to Zerg walls unintentionally - but this is a good change that should stay in the game.

Workers rallied through the wall into the natural while Rogue is under attack; the spore crawler blocks the wall for anything that isn't a worker, as the worker has a slightly smaller hitbox after the "worker only path" change. This is compared to small units like the zergling, marine, zealot - or in this case, the adept.
