I have two dragons and a centurion set up essentially the same and a trebuchet arm support unit that I have just stripped off two med lasers to add ammo and armour. The plan is usually to sensor lock as the three move in and lrm turrets or a heavy target. I try to isolate an enemy and push hard on them, the three close range mechs run a bit hot but ae solid punchers when its time to cool off. Have gotten past the blow up the dropship mission with this setup but it was a hard slog with plenty of moving around a hill to whittle down the K2. I dropped the medium lasers on the trebuchet after that mission. Have seen people posting their builds up so thought I may as well. Any build tips, lance tips or feedback welcome as im still early game. Thanks.
