I'd also add for important Hunter/Ranger equips
Hunters - Hell Raygun with around 50 ish hit, Charge Gatlings, Vulcans with hit as well. Usually go for a few PD's and are pretty stronk up until Ultimate mode and somewhat viable even then.
Rangers - same things but also Frozen Shooter if not a cast so they can at least help people in ultimate runs by freezing enemies. Also charge Arms/Baranz Launcher isn't a bad investment either.
Can pay a few PD's each for all of that or farm Restless Lion.
