My humble suggestion for improving Ocean Fishing

[Pepsi_Plunge]

And that screws over the other two groups on the boat still trying to get spectral currents. You can be a selfish ass and leave if you want, but don't try and pretend you're not doing a disservice to the other groups by doing so.

I don't think it really matters.
If the spectral doesn't trigger the highscore-run is over anyway, no matter how many stay or leave. I mean, that's the reason why people leave in the first place. Also they are free to do the same thing and take another boat.
And if they are there for leveling it doesn't make much of a different how many are still on the boat. Most of your XP comes from the HQ-fish you catch, not from the group bonus or how many points you get at the end. Triggering the intuition buff and catching those "bossfishs" are also something you do alone without teamwork. Actually, even for leveling you make much more xp by leaving after the first stop to boat another, because that way it gives you 4 stops total instead of 3 every two hours.

You only screwing people over if the spectral triggers but you leave after that anyway.
