Funny how people keep saying that it won't work, it won't work, without even trying it. Well, it works, and it's pretty damn frustrating, knowing the marines have ~4-5, or even 3, nodes, and you can't do anything about it. Last night, on eclipse, Dead_Meat and I tried to take down T-junction node that was electrified, while our hive was Maintenance. We bit the node a few times, went back to heal. Rinse, repeat - and this took ~3 minutes, enough for the node to pay for itself. There's just one example of how this strategy is quite useful, but it's more of a hit and miss thing - I'm sure the Aliens can do something radical and just win the whole thing right there. Maybe base rush? Or something.
