Team of 3:
This team goes straight to Graveyard (Mid) which ever side your on.
The solo player that attacks Quarry if on Red or Waterfall if on Blue should probably be a Necro or Elementalist
The thief should initially go to Mid with the team of 3 then check on Waterfall and determine if it is possible to cap it while also looking for an opportunity to attack their base.
The Mesmer needs to keep those portals between Graveyard and Quarry up as much as possible allowing for quick reinforcement if and when needed.
