Its pretty good XP and skill XP. I went out there around level 57 and forgot to turn on my loot scroll and got a Tungrad in about 10 minutes. Turned on my loot scroll and didn't see one for the next hour+.
Problem with Protty is its pretty small and not that far from Velia to be isolated. Most of people is lazy to sail there and you can always try different server if thats the case, but it can be populated. Idk why it doesnt have Marni realm, its one place that would be nice to have it considering size.
Protty in marni is 27k trash with yellow ls on succ zerker and around 1 bil/hr NA prices (650mil with 0 tungrad rings). I did 12 hours and averaged 6.3 atanis elements and 1.9 tungrad rings, so you were probably just unlucky. There are like 5 elite mob spawns spread out in the pond by the middle of the room, so classes that can clear everything in the pond with bsr can get up to a few thousand extra trash.
Well it drops Atanis Element which is a item you can use to make the infinite potions so that's the main one. It does drop Tungrad Rings and abyssal essence worth money too and you can get sycrid song for one of the krogdalo horse sets
