And to green guys too. Because ASM is most imbalanced and broken unit in game. With very cheap scouts, they are really unwinnable ++heresy redacted++. Even if you are ++heresy redacted++ with APM +- 10, you can easily win against all other factions.
All what you need for LSM competitive gameplay (step by step, because LSM players often...not very clever)
1. Get venerable dreadnought with ASM doctrine
2. Spam ASM as much as you can, mix them with scouts, get them power swords
3. My congratulations, another victory for the God-Emperor!
Even if you are monkey, you can easily win every game with such simple tactic. Good luck! (and please, stop crying about other factions. LSM is most imbalanced faction in game, you CANT be more stronger)
