People don't do fishing trawler for fun typically, they just want the outfit so that's why people are happy to burn more money. Also at a certain point it just isn't much money anyway.
I'm currently grinding to 90 range because the gargoyle boss has a healing phase and I really want to skip it, but I can't reliably skip it. 90 range is my next +1 boost from my ranged potion, so I'll be 5 levels higher when I get there and hopefully can skip the healing bit.
The only reason I did camdozaal stuff was for the hammer, it works for smithing and construction while being equipable instead of just sitting in your inventory taking space. The rest is kinda worthless afaik
