Just to point out that the creator of the list also included the "lost" (negative) bonuses from enchants/effects that can not be placed if the profession's own bonus enchant/effect is put on your gear (if you use Tailoring cloak enchant, you can not put a regular enchant on it as well). Also cooldown type bonuses, like herbalism's lifeblood (2880 Haste/20 seconds on a 120 second cooldown), has been recalculated as a "passive" bonus (as if used on every possible cooldown), so you can compare it to the truly passive bonuses.
While it is not the prettiest list in the world (of warcraft) it is very useful and accurate for 5.2 - not to mention the ONLY one i have seen around that is actually updated.
It would be awesome if one of the moderators here would make this sylancer's list a Sticky so all players can benefit from it's useful info.
While it might be obvious to more experienced players there is a lot of difference in "bonus flexibility" between professions, meaning that JC/BS can choose almost any stat as their bonus while certain other professions (like Inscription or LW) can only receive a very specific (but still useful) stat bonus for their spec.
