If you haven't picked up the Orbital Precision Strike since you were a noob, it might be worth giving it another shot. It could already one-shot Bile Titans and tanks, but was hard to use due to the long call-in time. But with that time being reduced to 2 seconds and the cooldown being buffed to 90 seconds (as opposed to 210 for the Railcannon) it should be much more usable now.
