Version 1 of the skill did not need bullets, version 2 and 3 do, NA is skipping directly to the third version.

Why are there three versions, and what did each version have? o-o

Because when you have something to change, you change it. And the overall result of the change is a new version. When you make two changes, you have 2 new versions, adding up to a grand total of 3 versions.

Ya, KR's final decision was the third version, which used bullets, only had one passive defense per skill, and slightly lowered damage (and elemental reforges disabled same update as second version but that's not necessarily skill related). JP got the final version of the skill from the start and so far the data suggests we'll be getting that version as well.
