I ended up buying it during the sale, and it looks like the developer took your comments to heart and nerfed the miniguns. The only thing they excel at now is tearing down buildings. They can't shoot through webbing very well, they don't tear through crowds with nearly the efficiency of flamers, if anything they're too weak to be worth the cost except to round out the team. Your minigun spam tactic failed spectacularly when I tried it, though I may just suck at RTS.

I do agree that robotics is pretty much a mandatory upgrade, and a medibot mandatory before any gun bonuses. The grenades I'm iffy about before you recruit a sniper because you lose the rocket strike ability and can end up taking way more turret fire than necessary. Helicopters are great for clearing out siege cannons and turrets surrounding crates, and they don't cost any ammo if you space them out a few seconds. The cluster bombs from the DLC are ESSENTIAL for saving nearby overwhelmed bunkers when your troops are otherwise engaged nearby. It's worth noting that whole-team tech upgrades require tech buildings that need to be protected from the aliens, which makes them tactically more expensive than their bare point cost.
