What 2 or 3 Guardian class tactical combinations would you use and how? I would use a hunter and Titan combo. Hunter would take the lead in open spaces and scout ahead or climb to vantage points while the Titan watches his back and moves forward to secure positions with hunter in an overwatch position. In confined spaces the Titan would take the lead, clearing rooms and wreaking havoc while the hunter sneaks around behind, above or below enemies using Titan as a distraction.
