Getting Destroyed by Teams in Blitz

3v3 is my favorite mode in Blitz because it makes me feel less stressed over how much land I have to maintain, as I mainly focus on 1 point and help my teammates when they struggle. I keep coming across an issue where 2 rank 40+ players are on the enemy team and work in unison to destroy me and my teammates entire armies. We were controlling the hill in between B and C with 3 blisterbacks and tons of locusts and other units to defend the blisterbacks. Suddenly the enemy team sent in 3 scouts, all of our forces were pulled into one point by one leader power and the other enemy leader shot a large explosive power that 1 shotted literally every unit we had on the hill. Is there a good way to deal with this? I tried to distance out my units yet this still always fails.
