Guild reputation decay gets a negative vote from me.

I feel like we need to separate gathering from creating in crafting.

Instead of just going to 4 lines of ability as opposed to 3, lets open it up to where everyone starts with two (or three if we change Fishing to this instead of a hobby) gathering abilities but allow them to get ALL of the gathering abilities via various methods (I am fine with this being store based as it is something we don't have now)
Farming (Food and Dyes)
Prospecting (Metal and Jewels)
Forestry (Wood and Hides)
Chest opening (Scholarly texts and anything else that one wants to put into them)
Fisher (Fish)

And then we all get two actual crafting Professions with the ability to add one more with store purchase or something. I am fine with starting with one crafting profession per character, but some already have two in the way they are set up now, so that won't work to take away from people.
Cook
Tailor
Jeweller

Woodworker
Scholar

I hate ingredients that are blocked behind Raids or other large group content. All ingredients should be available to all types of players. However, I am fine with certain ingredients being harder to get for certain types of players. Just not impossible such as putting things in Raids only. Maybe a Raid gives MORE of an ingredient instead of being the only way to get that ingredient.
