I got 2 randoms a few hours ago, it could be me being lucky, but I got all the good stuff (2x adventurers reroll, 2x captain reroll, 1 crew reroll, and 1 thing of the 10% seafaring (which I didnt had maxed out yet)). So its either me being lucky, or the max still is at 3. A little screen of 1 of the randoms with most of the random-based stuff.
