A recent devlog at the Pirates of the Burning Sea site talks about the changes that are coming to captain skills (your at-sea arsenal) with build 1.2. It looks like every single class will have changes of some sort coming. These will be in the form of global changes to certain types of skills, and changes specific to each class in the game. The global changes include: stopping speed buffs from stacking, reducing the morale cost of skills that cancel upon taking damage, and the addition of crew recovery rate increases and decreases to some existing skills.
The remaining changes coming to skills in build 1.2 are too numerous to list here, but we'll go over some of the highlights.
