Something along those lines Vys, yes.
However, right now you can put it to some use for defending - where if you connect everything through root network, and put some root nexus here, root nexus there, Sylvan gate here, and sylvan gate there - you would spare yourself the trouble of having to move your units from point A to point B. The firepower would be the same as if all units were attacking at once, but cannot exceed that firepower above your "all units are attacking at once" mode.
Which units get the attack buff - still beats me, I have zero idea. I could see it being "the first that can get the buff", given the attack cooldown. So that would be "the first unit that resets its attack cooldown". But now understanding this, I don't really mind it's functionality, I think I'll find a niche use for it. But just the fact that it took me 4 hours over 2 days just figuring out how it actually works (and how it should) is a thing.
Balance wise - it is fine and I don't want it buffed. But I also felt horrible when I was expecting it to do something ("supporting each other" part) - and it didn't do anything at all.
And why of course - I still give credit where it's due - you were of great help when figuring this out - and you have been helping me with tests too.
