Try to Continue or Start Over - Returning Player

Noticed some Lost Ark info popping up all of a sudden. Haven't played since release, but remember enjoying it. I got to lvl 34 as an Artillerist, but as I log in I can't recall any of the mechanics.

That being said, should I continue on with my Artillerist or should I just start another character to get acclimated to the game again?
