Looking for a new build

Need a few suggestions.

What I was playing before was a Dual Wield pistol / Rapid Fire Commando using the Firestrike line as my main DPS.

Whatever changes have happened since I last played ruined that build to where dps’ing a field rat in Ult is near impossible.

Trashing that toon and wanting to make something that covers both magic and physical damage in case I run into a mob/boss that’s immune or highly resistant to one or the other.

I prefer ranged combat over melee, and I have no idea what items in the game are best for builds now.

If anyone has a suggestion on what to take a look at I’d greatly appreciate it.
