For my condition WvW set, I use the “Dire” set, its main stat is condition damage and then subs are Toughness / Vitality, this is more of an outlasting style play though, but with these stats it would be easier to go into the illusion tree without forgoing to much benefit lost from chaos. I also have the travelers runes on this set, and as an aside, I generally roam with my good friend who is a thief so its an awesome pair to run. But I have had a lot of solo success with this set.
