Guild Wars 2

Feel a little overwhelmed. Will my build still even be viable? Using sword and pistol combo. I used to rock PvP.
Where should I start reading?

Gonna need a bit more info than that. Sword/pistol Greatsword shatter?

For now, run with Dom/Dueling/ Inspiration OR Chaos

Power Block (or Mental Anguish), Shattered Concentration, Confounding Suggestions
Phant Fury or Duelists discipline, Blinding Dissipation, Deceptive Evasion
… anndd whatever you want.

Marauder Ammy. Energy sigils, some fire/air thrown in. Lug around a greatsword and you’re good to go.

Runes of Lyssa, Strength, Eagle, Hoelbrak, Air, Traveler (bleh) or Pack work fine.

Edit: Alternatively, you’ve got options for Lockdown, Boonshare (yaaa it’s kind of a thing now), and Condition.
