It's not wrong to go with 2 or even 3 penals before a scout car if your not getting enough impact from the early car. I would also recommend checking out some map guides such as This one by Jesulin If you improve your capping order and position your units correctly, you will put yourself in the best chance to win the first engagement. ex. penals coming from two angles, attacking where there will be green cover, using houses to scout or stall.
I'll make sure to have a look, thank you.
I'm aware that I have much to learn and I guess that's why I'm here.
