I wonder which professions I should choose for my druid? Alchy/Herb or leather/skinning or any other professions?
So i need some help to choose...

Go for alchy/herb, you will use potions a lot more that you need self-made leather armor (and the leather armor that drop from mob tend to be better, and you can buy player made armor from other players).

How do you unlearn your profession?

Pull up your character sheet, choose the skill tab and find the skill then click on it There will be a very small circle with a line thru it just at the top right of the skill. Click on that and you will get a confirmation box to delete that skill. Confirm and poof! it's gone.

I woudl say, dont go alchemist, go Tailor, u cna get good stats for intel/spi for mana regen and spellcasting and u dont need armor... u got shapeshift...

So anyway, pick what you think is going to be most beneficial to you. There are times where I wish I was an engineer, and other times I wish I did enchanting etc. Currently Im an alchemist and I benefit from it a lot, but I hated skilling it up. They are all a pain so do what you think you will get the most benefit from.
