But of course, the pulse are short range so if you want to go long range it’s better to use tachyon than pulse. Especially since the paladin can afford the PG cost and a MJD to put itself in perfect position.
Anyhow, if you intend to shoot at range, then it’s 100+km and aurora is just better. If, however, you intend to let the rats come closer to you, and even can shoot the BS at their orbit range, then it’s 20-50km that you are interested in.
The tachyon vs pulse is not about the raw numbers : it’s about two very different ways to play. With tachyon, since you MJD, you have no issue with tracking but you basically have a constant 1200 DPS from 90 to 150km, 2k from ±50 to 90.
the pulse means you do more paper DPS, but since you are basically 50-km from your target, it also means you need application modules - though drones can help alleviate the small fries.
