I've had this thought for a long time by now.
I feel like the horticulture skill have no more purpose then finishing the achievement and beeing able to craft those flowers. You could achieve both these things without having to level up horticulture.
To get to the point, we have made other skills more inportant before by adding new features to the game.
If you could somehow mix the organic materials with each other by brewing we could make it more inportant to level up horticulture. These potions or items you make could have varying effects on your other skills and preformance. This way I think the game would be even more fun and it might just attract new players to the game.
Horticulture would be a skill that is used and so many items would all of a sudden have another way to be used.
The game would be broader so to say and the skills that are already developed would be used in a awsome new way.
What do you think?
