Guild Wars 2

With Duel I gain lots of survival traits, clone production and perma fury, but Illusions are just too useful for the CD reductions, AoE daze and other gimmicks. What’s the superior choice if I’m running Berserker gear? Thanks in advance

Dom/Dueling/Chrono is going to be your standard DPS build.

Dueling is going to be interchangeable but only to Inspiration if you need reflects.

Standard PvE/dungeon/raid setup for traits:

I suggest checking out Sanderinoa’s guide on Dulfy’s site:

The link should take you down to the Chronomancer part. It has good details and several builds with variants.
