For everyone that wants to talk directly to the Halo Wars competitive community, I recommend checking out the Omega Team discord. Here is the link. You can talk with all of the active and competitive halo wars 2 players and ask questions about strategy in a low threat, chill environment. You can also find players that would be willing to coach you through builds and help you pick up the game quicker. Many of the members stream their tournament games so you can directly watch the highest level of play, every weekend.
I also highly recommend RTS_YODA_VIDS and Nakamura_RTS for streamers as they are both very accomplished players and they often hold show matches where they offer great commentary on what each of the players does right and wrong.
If you are starting off with the game, these are the best 3 places to improve your game.
Go to yodas website: consolerts.com. It’s coming together well with detailed breakdowns of leader powers for each leader and units etc.
