Hey guys,

just noticed swift attack and saw that it means that you can attack twice as a full action. But don't you already have that with two standard attacks?

Does that mean that you can use standard attack only once each round?

RAW, you're only allowed 1 attack action per turn. You can't take 2 half action attacks. You should read the errata - it clears up a lot of how Swift + Lightning Attacks work.
