I've been cannith crafting ever since it came out (update 9 in 2011), I stayed at lvl 100 until a few months ago when they had a significant boost to crafting XP (30-50% i don't remember) and then I leveled to 140-145 for the flexible recipes.
I accumulated a lot of essences over the years, so i had enough.
I don't craft much. I have my BTA twink gear +4/+6 stats, heavy fort, false life, secret door detection, true seeing, alacrity, etc. I just pass it around my characters.
