I've noticed when mining if you equip the mining axe you mine faster.
However with farming you only have the Water can and shears. The water can can't be equipped (but still has dps stats???). So really you just have the shears (no dps stats-another oddity).
Could we have other tools which reduce the action times of our farming?
A rake and a shovel would be nice.
This might even get people to group more while farming as people might work together more to increase yields and speed up farming overall.
