Guild Wars 2

so i have had 1 precursor since i started playing and it was a zap, i am going for twilight so i need a dusk, but what i wanna know is whats the rough chances of getting a precursor in chests/dungeons etc if anyone knows it’ll be great

Almost inexistant. Consider yourself very lucky with 1 precursor.
As many players, I’ve put a bit more than 1000h into the game, probably half grinding stuff (Dungeons, Orr farm, etc) and never got any.
Havnt tried the mystic forge though.

Unless there is another bs karka event, which you could try to exploit with many alts or overflow servers, etc etc etc.

I wouldn’t hold your breath. I’ve got over 1500+ hours played and all i do is dungeons/dragons and i have never seen a precursor drop for me. Even during the Karak event i didn’t see one drop and that was running the event with 3 toons. I got lucky and had saved up 100g towards kudzu before the Karka event and then after that, all precursors crashed in price and i scored leaf of kudzu for 100g

I think MF is your best bet atm but even there, you can search posts and see many horror stories with that in itself.
