A few common misconceptions:
-Being an engineer doesn't mean that you never have to shoot. In fact, if you're a gungineer, you'll spend most of the game shooting.
-The balloon isn't the most important target on the enemy ship. Most guns are weak against it. Target the hull unless you're using a carronade, lumberjack, or maybe a flamer.
-Hitting a component during its cooldown doesn't do anything at all.
-Ramming isn't a dumb, brainless type of manoeuvre. A good ram actually takes a lot of skill to pull off.
