Blacksmithing beyond 115, worth it?

[OfficeThug]

Hey everyone, I'm a bit new to the game considering I haven't played since, well, 10 years ago and barely even remember what it was like back then. This time around I decided to take up Smithing to make a small profit as a lowbie. Now I'm sitting on 115 smithing skill and the ability to make and sell banded armor for a good profit, at which point I figure it'd be nice to move on to bigger things. I check out the next recipes (ornate chain or fine plate bracers) and realize that the cost of failing to make these things to sell-back is horrifying. Additionally, I'm not even sure which recipes are available on Classic, the lists on the Trader's Corner take into account that all the expansions are available, so I might just be skilling up to make hyper expensive things no one will ever want as far as I know.

What are your thoughts?
