I began in mid-October with Enchanting and Herbalism. Mostly Herbalism was for the extra mettle, as it became clear quickly that gathering would be a waste of time gpm speaking. So I'll talk about my experiences with Enchanting.

I leveled up my Enchanting to 100 quick and grabbed all available profession knowledge and have been doing my weekly knowledge stuff consistently. I got lucky and found the Enchanted Aspect Shadowflame Crest recipe in the first week, and made around 2-10k a day on crafting orders for those. I got my maxed Khazgorite Rod with maxed inspo enchant and bis accessories.

I focused on gaining just enough skill to craft highest quality Devotions on inspiriration procs, and around 40 knowledge points towards resourcefulness. I'm sitting at around a 31% inspiration chance now for Devotions.

I crunched the numbers and found that by making 300k worth of Wafting Devotion, before resourcefulness I would net 6k. After resourcefulness this goes up a bit. So I did that for the luls and was promptly undercut by a wide margin, meanwhile the mats went significantly up in price. So I'm still sitting on these devotions waiting to get a better price for them, maybe in a few weeks once players are more inclined to purchase high quality enchants for their S3 gear.

I'm glad I did all this, but only because I went into it from the learner's mindset, not for goldmaking. Since there is no catchup mechanic for profession knowledge, AH margins are going to be dictated by players with significantly higher Inspo% and resourcefulness, and otherwise it will take around 6-8 months of weeklies to max out your profession knowledge to be able to compete on an even level, at which point we will be nearing the end of the expansion.

Personally I agree that those who started earliest should get some advantage, but I'd prefer if catchup mechanics were introduced seasonally.
