Tailoring profession and crafting profession goods

It it a design choice to make it dramatically more difficult to craft higher level profession gear for tailors? I have alts with all the professions and they all have skill trees that allow them to reasonably be able to craft highest level profession gear with 60 points or so. In contrast, all the skill nodes in the tailoring tree do not seem to benefit crafting of profession gear (and tailoring has a lot of these items). It is exceedingly difficult to craft profession items above level 544. For example, putting points into the first node of “textile treasures” would typically (in other professions) provide a point toward crafting tailoring items. Instead, does it do nothing other than make cloth drops more likely after hitting the 5 point checkpoints on the node? Is this intentional? Are there any options in the tree to improve your skill at profession goods?
