Well, if you want Tigerspite, that generally only drops in the Dreaming City, usually either as bounty or quest rewards, or from chests. I've gotten six that way. I've gotten several Ether Doctors with crap rolls. That's RNG. You are seeming to forget the Go Figure, Right Side of Wrong, Misfit, the Duke, all the Dreaming City weapons like Sleepless and Nation of Beasts. I could name another dozen guns that you didn't mention. So that's RNG. This game has always handed out sets of armor for particular rewards, connected either to a planet or the faction in question. Has since the beginning. I've gotten one Forsaken exotic weapon in Lord of Wolves. A few Forsaken exotic armors on my warlock. There's not a small loot pool. You're either cherry picking from confirmation bias-I've gotten a metric ton of Misfits so it would be easy to think there's a small loot pool-or your RNG is bad.
