This has bugged me since the 1.9.1 release. In Plunder Pirates, there are no projectile weapons that require re-arming. I don't understand why PH9's cannons need re-arming. The Shark Trap on the other hand behaves a lot more like Mines / Mystic Mines / Flame Gates. If anything the Shark Trap should have a re-arm cost. But then again it never seems to clamp shut before being destroyed so one has to ask, "If a Shark Trap shuts but there is no one around to see it shut, did it ever shut at all?"
I see shark traps close a lot. It doesn't have to be rearmed, which surprised me at first. But when I'm raiding with thieves, if I can't easily snipe it with a gunner, I send five thieves in as my first wave to trip the trap on them, then send the rest in another batch or two since its out of play. I do think that shark trap should behavior should be more clarified, it should probably have to be rearmed (the loot chest inside needing to be re-filled!), and that PH shouldn't need a rearming, or it should be made more clear to players that it does.
