*** Posting the solution of The Dawn of Don - which doesn't require you to start a match with a friend ***
Players: 1v1
Map: Blood River (1v1)
Mode: Deathmatch
Difficulty: Normal
Forge vs any Covenant (I prefer the Prophet as his power is the easiest to spot)
Build a vehicle depot and queue up Grizzlies and Cyclops. Capture the two other bases on the map. Place two Grizzly Tanks and a couple of Cyclops at the bottom of both slopes that lead to the enemy's main base. Use your Warthog to scout the enemy base to see if he built a Temple. If he didn't, either destroy a couple of buildings with your Grizzlies or restart again until he has a Temple. When the enemy hero attacks (I was up against the Prophet), release the disrupter. After one disruption, the achievement should pop. If it doesn't, kill the prophet, wait for him to respawn and repeat four more times (here, the Emperor Skull might come in handy, as it reduces the recharge times of your Powers).
I played on an Xbox One.
