Trade skills (am i missing one) ?

How is grinding through all the skill ups to get a BOP trinket from alchemy better than grinding through all the skillups to get several BOP armor items from leather working? 1 Trinket vs 3 pieces of Epic Armor...

I think you misremebered my post. The point was I trying to get across is you might have to do several reputation grinds to get all of your professions up. I might have spoke a little too soon but I think that getting recipes from various quartermasters will make the leveling of skills easier.

so for example for your leather worker you grind ogres to get your Kurenai/ Mag'har faction
for your jewelcrafter you get your Shattered Sun Rep up for various recipes.

I am sure there are more examples out there. I would look at powerleveling guides to see what level of rep you need with various factions.

Rep vs Skill ups....

My other thought relating to this post is that it has been stated that many (possibly all?) epic and rare patterns will be achieved via profession specific dailies and the credits that they allow. It's gonna get pretty annoying trying to do 6, 7 or 8 different profession quests on various chars (although less annoying than solo boxing them I guess.
