Steamrolling
Definition
A term referring to the strategy the entire team uses to move through the mission as fast as possible, decimating all enemies in their path. This is basically like normal play, but at a more advanced pace. Typically, the team will have access to a mixture of high damage powers, damage buffs, defense and/or resistance buffs, healing and recovery to prevent the team from having to rest as they steamroll through the mission.
In many ways, it is considered the opposite of herding, as the team moves quickly from spawn to spawn, and is not overly reliant on a Tanker's ability to herd. Instead, more emphasis is placed on the Tanker (or whoever is leading the team, such as a Scrapper or Brute, for example) to lead the team's direction after the spawn is defeated in order to minimize waiting time and to avoid splitting the team.
Many archetypes find they may well go into the Scrapperlock mentality of attacking whatever is placed in front of them, pausing only to keep an eye on where the team moves next.
