I was in the same boat as some of the commenters in this thread when I first hit 45. The amount of gold needed to upgrade or the amount of time to craft the things I needed was going to take 7+ days for 2 lvl. I was overwhelmed.
But don't fret. I've been 45 roughly 10 days. Grinding out dailies for gold, farming for mats, dungeoning for recipes.
Without much effort I've upgraded to a true profane weapon, started stock piling soulstones (48 atm), and I'm sitting on 15g with a 14g gem in my bag waiting to be sold. It's fine guys... Just do ur dailies and farm
