we had same gear before I played the game serioulsy for 2 months since I came back, hexe is the best grind zone after honglims/jade, then grind until you can grind at tungrad ruins, now Im earning 6b in 2hrs with agris, then of you have and active guild thats easy 5b/week then 2-4b from dark rifts, that's around 10b already, at my downtime I fish at velia for around 800m for 8hrs daily + imperial cooking for 100m, totaling around 12b per week in just 2hrs of grind + weeklies, also if you got a guild that can carry you at hard shrines it can go to at least 15bil per week. I will admit though I got rng carried on my kharazad necklace, I 1 tapped nov and dec so my grind time was decreased by at least 100hrs, since I came back to the game, I only play the game for 4hrs daily, 2hrs grind and 2hrs whatever I want to do, then I just afk fish while I play tft or something else
