I just recently hit 80 on my first toon. Having hit level 55 I found out how leveling a crafting from 0-400 gives you 10 levels. So I looked up the cheapest, of which is cooking. All up it took me about 40 minutes, all of which was looking for a guide of what to buy off of the trading post, buying the items, equipping my crafting booster an as for the actual 0-400 took me 27 minutes.
I was then level 65. I bought a set of Lvl 65 gear of the TP as my current gear was lacking. I leveled to 70 and decided ok it's time craft again and decided on artificing. That one took me longer as the guide was more focused on discoveries. The actual 0-400 on that took me roughly 40 minutes. Needless to say I bought another set of gear off of the TP.
All up the cooking cost me between 2-3 gold and artificing cost me a little over 4 gold. Yes it's awesome I am now 80 but I feel like I have robbed myself of some awesome content that I will probably go back and see at a later time on this character or a new one.
So my question is.. Do you like being able to level so fast with crafting or not?
I can't remember how many crafts are in the game but if you had a lot of gold backing you it seems you could make nearly level 80 in one day. Is that too much?
