build/gear condition without expansion
If you do not have the expansion then your best gearing strategy is just going straight Sinister in every slot, I believe.
I don’t believe the expac added any Sigils of note, so you will be able to use the same sigils you otherwise would, with an extra emphasis towards condition duration sigils. In particular, I’d be looking at Agony as a mandatory sigil, though this depends on what content you’re targeting- if mobs die before your bleeds tick out, you may want something else which applies more conditions or grants more condition damage.
For runes, I think you can buy Rune of the Berserker as a non-HoT player, but I am not sure.
dire with krait runes, have fun
Is dire still a thing for condi? I thought it was out performed from viper/sinister, no?
Gear depends on what you want to do.
Dire is bunkerish, Carrion is more aggressive, Sinister is most aggressive.
Krait runes do well and are cheap.
