Dungeon finder : A good idea that flopped, pretty much nobody use it.
New questlines : Go to Withered Land (griff at Thurg harbor on the other side of the docks) the solo - and easy for a necro - questlines will give you enough stuff to start the heroic content. While you're there, hunt the named they have nice rare Fabled drops (even if you can't use them, the WL fabled usualy sell well) The heroic access quests in Skyshrine give some nice rewards too.
AA : Not much changed since DoV (AoD gives 20 more AA but with no new tree nor more max AA per tree, it's just filling)
Crit mit : It's gone now, you still have to have enough crit chance to crit 100% tho.
Wands : meh... useless for pure DPS (about 1% for me) but it helps with procs so it isn't that bad. Spell weapon stats are good candidate for reforging (SW DPS first and SW haste only if you have to) other than that... /shrug
TL/DR : Do the WL questlines to get new gears. Go to your favorite grind spot and level to 91+. Start your own group for Skyshrine's access quest/faction grind.
