Marksman Building?

It's kind of stupid, really. If you're not a NL, you stand to gain just about nothing from having SE, and if you are, you still get 2/3 the benefit for 1/3 the points. But then again, it's also stupid that 1 point of attack can cost millions, and I doubt that'll stop any time soon.

RE 30 Boost vs 30 SE in numbers
Since they multiply each other, it's probably actually more beneficial to have something in between the two scenarios presented above, assuming you don't mind being thrown out of parties by stupid people (i.e. everyone).
Ex. simplified example:
10*30 = 300
20*20 = 400

So yeah, I hope us Corsairs start filling up attacker slots in squad runs. We don't care what level SE you have <3
