Absolutely perfect optimization may involve mixing one or two pieces of Sinister with your Viper, Assassin's to cap out crit chance with power builds, or suchlike (consult Snowcrow's for raids, discretize for fractals or MetaBattle for details), but for simplicity's sake I'm focusing on those four stats. To keep this simple, in 9 cases out of 10, you're aiming for Berserker stats if you're direct damage, Viper stats if you're condition damage, Harrier stats if you're a healer, and Diviner stats if you're a boon support. Now before you go grabbing exotics and ascendeds, you need to figure out what stats you're actually aiming for. Weapon is a bit harder than trinkets, so don't feel bad about picking up an exotic while you start working toward the ascended, but at least one ascended weapon is generally standard for more serious raiding groups, because the base damage increase makes a huge difference. Don't worry about the offhand right away, but you may need the mainhand of the 2nd set depending on your class's standard rotation.

The other thing you should work toward is an ascended weapon for your primary weapon (the 2-hand or main-hand weapon you do your most damage with typically the melee weapon if you have a melee set and a ranged set). The thing you absolutely do want pretty much as soon as you hit 80 and know that you're going to take this character seriously are ascended trinkets (amulet, backpiece, accessories (a.k.a. So go ahead and forget about ascended armor until you're at least in tier 3 fractals, by which point you've hopefully had an armorbox or few drop for you. Raiding doesn't require AR, and the stat increase is minimal. Tier 3, it'll be slightly easier to get the Agony Resistance (AR) you need with a couple pieces of ascended armor, but still doable.

Tier 1 & 2 fractals are absolutely fine without a single piece of ascended armor. First and foremost, exotic armor is fine for literally all content except tier 4 fractals. 4.2 Viper/Harrier/Diviner and Stat-Selectable Armor.2.1 Living World Trinkets (aka easiest trinkets).
