I can see Blizzard's reason for making tailoring the way it is, but I'm a bit disappointed. It's no longer a must have like it was in the Burning Crusade where I had tailoring on every cloth wearer I rolled. I dropped it on my mage, and will keep it on my alt so I can make bags. The flying carpet looked cool, though, but wasn't enough to justify keeping the profession when something else might be potentially more useful.
Now I just need to decide on a second profession. I'm toying with alchemy, inscription and jewel crafting. All of which have plenty of self-benefits. Not sure if JC has as many, but I've always wished I could cut my own gems instead of having to track someone down every time I got a new item. That's the same reason I ended up taking enchanting.
The self benefit of tailoring is that it's stand-alone. Not that that's really a benefit, but it's still the reason why it gets a weak self-buff.
Blizzard gets to know that most of the people take tailoring along with enchanting, which much like some people take mining together with Blacksmith or herbs with Alchemy. Both mining and herbs have a benefit but it is small and negligible compared to what you get from Blacksmith and Alchemy. In return, mining and herbs make it easier to level Blacksmith and Alchemy as well as tailoring with enchanting. Enchanting gives a good noticeable buff, tailoring gives a mediocre hardly noticeable buff. And like the former, having tailoring makes leveling enchanting a whole lot easier by having a reliable and renewable source of enchanting mats without having to rely on alts with gathering professions or quests that eventually run out. By giving tailoring a noticeable buff like enchanting, most of the people who combine other archetypes will get be forced to take two end-product professions to get the same amount of buffs, two professions that can't be leveled without the interference of either a gathering alt or lots and wow gold.
That is to say, it makes sense when you think of tailoring as just a gathering profession for enchanting. It's not the same, tailoring obviously has its own crafts. But because enchanting and tailoring get paired so often, it's reason enough to threat it as such. It's the reason why I suspect tailoring has melee embroidery, because many people who level enchanting as they level their character take tailoring along with it to make things easier even if they dump it afterwards. It is necessary for you to power level a different profession along with enchanting, much like every other profession has to if you want another big benefit to go with it.
