This is simply my opinion, feel free to add yours below.
I appreciate the skill's usefulness and the simple game design of how skilling works, ***the feel of the Farming skill just sucks. ***
It feels like I am planting a seed and then watching a single plant grow in a pot that sits on my second floor window. Not farming anything substantial where I actually need a rake.
I'm not really looking to toss out specific changes, but the normal skilling timer of processing a single seed at a time just doesn't deliver the same "game feel" like it does in several other skills. This is especially true when going down to lower seeds.
I am less than 25 total levels from 2400/2400 on my GIM -- and looking back on the skilling portion of the journey, I simply think this skill should have a different feel much like enchanting does; where it can be "trained" while other things are going on; just incorporate timers for the "growing" portion.
