This is true because of CRZ in outlands (god I hate that). However blacksmithing takes more ore and I also consider JCing to be harder.
Fair point. The profession is still one of the strongest for challenge modes and offers other great benefits (shrine AH, repair bot, etc.). So it is far from 'rare'.
True but one month really isn't all that much in a WoW setting.
Exactly, and leveling engineering costs 5-10k max if you aren't on a dead server (last time I checked leveling ore prices on my realm was 2 months ago I might add).
But even if you are on a server with a dead enonomy then there likely won't be many people with tons of gold so even then you won't be able to sell.
(Getting the recipie is not even worth mentioning calling it 'uncommon' would be a stretch.)
The golem is a buyers market and many people will be disappointed . I'm even thinking of buying a few up cheap and trying to flip them after the first week.
(Most people probably won't bother going through the trouble of making a second one after not reaching their expectations.)
Between the 2nd and 4th week it will probably be wise to resell tho just so you don't run into the second batch of people who learnt the first one themselves.
The main problem with those is honestly how easy the content is. In 4 lockouts (so no spirits of war) even most casual guilds worth their salt will at least have 10/14 bosses down which means tons and tons of loot. This quickly limits your market to LFR + flex raiders which don't tend to spend 50k+ on their gear.
So I wouldn't bank on selling more than 1 or 2 pairs for an ok price.
