And although it isn't "content", they also added Potions and Fishing levels to the weapon card, which is pretty cool. I like to see those big mastered pirates who have been slacking on their potion brewing duties haha
The new daggers are cool, and VERY powerful. Some of the skills, like Backstab, really make me feel like an assassin.
The throwing knives are great and give A LOT of rep if you use them right. Since they do less damage than daggers, you can strike more times (depending on your skill point placement of course) and I continually get the maximum rep capacity without wasting an asp, adder, sidewinder, or viper's nest.
