While the patch on Tuesday gave a (slight) increase in drop rates for saltwater fish at fishing nodes, Saltwater fishing is still awful to try and achieve. I have now spent over 40 hours collectively trying to catch the one last fish I need (the Aurelian Herring) with no luck. Not 40 hours to complete the entire achievement, no, it has been 40 hours of constant fishing trying to get that specific fish, sitting at 13/14 in the avid saltwater fishing collection.
There is no fun gameplay in this, no reason why it should be this exceedingly rare, especially when all of the other fishing achievements were much easier and well balanced, not requiring any massive amount of grind to complete them.
My proposed solution is to adjust the rates to be similar to that of the World Class Fisher achievement, and to make a node like the one in Kessex for Saltwater. It would still take time to complete, just not the ridiculous amount of hours that it currently takes.
Please ArenaNet, this one achievement has effectively ruined my experience with fishing in this game. Don't make others experience that as well
