The grind is generally a simple concept but these are some criticisms I have of the current system:
- Tree grinding takes so long and the player cannot do anything to effect it. For example in the old system of seed purity grinding the player if he so chooses can do extra work to produce charcoal to speed up the field and hence speed up the purity grind. With new system you cannot do anything except stare at the pot for a week.
- Tree grinding has a random chance to completely fail - and this chance is rather high! Gardening pots for all other stuff never fails, farming never fails (Sure the purity may have some random adjustments but you never completely fail to produce) but trees fail, and fail often. Not only that the cuttings never grow back so with just two cuttings you the high chance of failure you are quickly going to hit dead ends on tree purity. You'll reach some purity and the offspring will fail and then you have to start from scratch!
- It generally does not make much sense. The old system was very logical and was based very much on natural selection just like the farmers of old used to do... you plant a crop and on harvest time you take the seeds from the strongest plants or rather the plants that most exhibit the properties you desire and you replant those hoping to produce another generation even better in that regard. New system with compost bin and worms being the key to the quality of the crop... is quite illogical.
