I thought of a (potentially) fun way to give you guys some ideas to think about formulating your own base designs, with the help of a few challenges. If you guys like it I can turn this into a series.
The first challenge is: let’s say the board is completely empty. The opponent launches a scary 5 EMP stacked attack from a spawn on 8th row (so somewhere in the middle). You are given unlimited cores and know exactly where the attack comes from. You are not allowed to spawn any units, and the opponent is not allowed to spawn any firewalls. What is the least amount of cores you have to spend to stop the 5 EMP’s from scoring at least 1 point? And what layout do you use?
Of course you can find the answer directly in the playground, but you won’t learn anything that way so I don’t recommend it. Maybe use pen and paper (that is what I did to answer the question). The most fun way would be to directly post your reasoning here without checking for the answer first. I’m interested what you guys come up with!
 IMPORTANT: If you haven’t tried the problem yet, don’t read the discussion+solutions below!!!
