Why is this specific hacker’s version superior to similar colosseum hacks (like Akogare’s Arena or The Pit V3)?

Because the rush meta is dead, the enemy cannot close the distance quickly enough to interrupt your setup. Torakutori is better because v108 effectively removed the counter to area denial: speed.

For Engineer players, a map is only as good as its sentry spots. V108 offers a fascinating meta.

Torakutori successfully walked the fine line between giving Engineers strongholds and preventing the map from becoming an impenetrable fortress.
