I get that the volcano area is supposed to be terrifying. And it should be high-risk-high-reward. But the volcanoes have skullfort-canon-level aim. Considering they erupt ever 2-3 minutes when you're close, their aim should be toned down a bit.
Either that or make them erupt slightly less often. Today, in the space of less than fifteen minutes the same volcano erupted three times and sunk four ships. That there, should be an indication that they need tweaked...
