You may, or may not, have heard that SOE will soon be implementing changes to the harvesting tools. This is directly related to the changes coming to harvesting time (i.e. they are going to reduce the harvesting time across the board).
The short version is that they will be merging all standard crafted (i.e. non-tinkered) harvesting tools into a "Harvesting Kit" which will work for all harvest types. Additionally; they are going to modify the harvest time reduction granted by the kits and also add a chance to double-harvest.
You can read the full details in the forum post over on the EQ2 Forums.
