Well the best way to get ascended gear for me is doing the pvp league. By the time you finish all the chests, you have basically made almost 150 gold, you get plenty dyes, and you get 3 marks you can use to purchase a light, medium or heavy ascended armour. The added bonus is that the ascended armour acts as a precursor to legendary armour which is not too difficult or expensive to get in relation to the other legendaries. As you do league you can go for the league achievements which will ultimately allow you to get a legendary backpack, and if you dont want to spend your cash, you'll at least get an ascended backpack. AND you will also get rewards from whatever reward tracks you use (potential ascended rings drop from them, i've gotten like 5). The only downfall is...if you hate PvP. The ranking system is pretty broken when trying to matchmake so a lot of the time it is a lottery with your team. But anyway, that will keep you busy for a long time and make you rich quick.
