Houston, we have a problem

Yes, I know what Fusion Bolt and Magic Fusion are.

And since when were 'one rank skills' officially called Actions? The official actions are those in the Action Window.

Normal Attack technically shouldn't even be an action, that was just implemented for convenience. It still utilizes Combat Mastery and Ranged Attack.

That explanation was a reply to Infodude's post about fusion being a skill.

Weren't the old gathering skills actions?

They were skills, just like the current ones.

All the Actions are technically Skills.

They couldn't have been "skills". Otherwise you wouldn't have been able to get points in production mastery for doing something "without using a skill".

The server decides whether or not to give you exp, not your client.

Yes, but what the client displays is how we usually pick the terminology. Though that line could have just been more of Nexon's famous typos and inconsistent/imprecise/inaccurate wording.
