Craft outside event, and lvl up during gear crafting event. If you have atlas for long you only need around 10k scrolls or less to get full set legendary. I got full set legendary less than a week maybe it was luck but im just sayin. Leveling gears is main issue.
Took me 12k scrolls and i got my weapons very very quickly
This was I crafted it before the seasons started so sadly I got a few upgrades on the legendary glove before elite came out. Guess I can still use it in the future when the elite gear is completed.
Half way through the third set, this is also on a f2p budget.
