I theorycrafting a little bit with the Early game of the marines.
First to das i dont like ASM spam so i dont want to use it.
So i think about a Scout Opening.
I would take 2 doctrines. 1. Is the cloack for sniper and 2. The plus damage out of cloak die scouts.
So scouts scout and the sniper shot in longrange on the enemys. When i have melee attacking, i use scouts for Stun and Burst damage while sniper do the main damage.
And if the enemy is to strong all return into stealth and regroup.
Ja this a Way how the game could work for Marines early?
