After gaining the compression technology, both the depth and breadth of a Mechanic's combat abilities would drastically increase. They would gain the ability to take control of the situation or even turn the tables immediately. The focus was to deploy the machinery as fast as possible and the right combination of machinery at the right place. The speed of deploying that machinery would have a very large impact on the outcome of the battle.
After the version of Mechanics rising, the method that other Supers used was mostly striking and charging before the Mechanic could deploy their machinery fully. If a Mechanic was allowed to deploy their weapons freely, the situation would be irreversible, and the enemy would slide down the abyss of failure. Of course, this was in the case of normal situations, not considering some special abilities or items.
