Dire vs Rabid vs Carrion?
That sort of thing is probably easiest to figure out by playing around with a build calculator such as http://intothemists.com/ . Since it’s harder to swap traits than gear it would be better to figure out what traits you want first.
First, condition damage in PvE is generally crap because of caps. If you are at an event with a nerco and a SB ranger, you condi warrioe will not make much difference. I would stick with your zerker warrior for this content.
Having said that, I just geared a condition necro to do husk patrol at the new wurm event.
This is what I went with:
Armour: Carrion with runes of the scavenger
Trinkets: Rabid with crests of the rabid
Weapons: Rampager with sigils of bursting, corruption, blood, etc.
All of the above are exotic. I didn’t see the point in investing in ascended just for this.
