It's your gear as other people have said before. You can probably just buy from the NPC's if you're not rich enough to afford some HQ sets from the Market boards and be fine. Can get everything but your accessories. Though if this is your first time through, quests will give you gear as well. But i'd still buy at least the npc gear atm until you get that far because 6k as a warrior is extremely low for Heavensward content, as a WAR.
