Hmm I don't agree with much of this, but we all have our own styles don't we
I like shoot and rapid reload. Both make firing faster, and I have them both max'd.
I also max round shot.
I don't use the other ammo too much, except grape, I have 1 in that. I didn't even unlock firebrand this time.
I will use Thunder to tag ships that are way out there, and if a ship is coming too fast, I will use it to take down the sails faster. I like to have that max'd.
I'm not a fan of fury. Only have 1 point in it. I debated not even opening it. Probably won't with my next pirate that I make.
I didn't unlock barrage with this pirate, only because I do not want grenades to do a lot of damage until I max it. It's hard enough to max grenades as it is.
Explosive sounds like a good idea, but I would only use it in an emergency, and you really can't since it takes so long to load.
Other thing also, I find it kinda annoying to always have to run to the ammo shop after every run. And if you're filling up a WG, I would think you can run out of ammo.
