Fishing should create a "hate" that over large extended time periods give the goblin BH the ability to agro even a 75. Then again change the names of the Bounty hunters to "wildlife and gaming commission" and issue fishing permits. The goblins then can crack skulls for violation of their fishing permits!
(this started as a random humor thought, but might actually be viable in some fashion).
purchase lvl1 charged item. charge gives status effect that lets you fish goblin free for timeperiod (somewhat random duration, like 30 min +-10 min). fishing without over time enables them to agro you (and summon a level appropriate foe). Limited purchase of said charged item or something or just keep logs of when players purchase them for trending.
