Let's begin morning prayer with the mantra "Hommm, I have to experience it myself before commenting, hommmm", but overall I don't mind the changes. If they are detrimental, there is a long A19 dev cycle to complain about them.
I think I've got a solution to this (and it seems yes, there are players who want grindy activities to "support" others and it might make sense to not ignore them). While it is absolutely too early to post this idea, well, before I forget it:
Basic farming should be like in A18, non-grindy and just costing materials. Because lets face it, most players probably see farming as a grindy necessity, nothing more (*). But there should be a further optional level where you get more resources from your field by regularily tending to your farm plots (watering or tilling).
It could work like this:
1) harvesting a plant produces a plant OR a seed (ration 5:1). The crafting of seeds from plants is either gone or a rare recipe.
2) Watering/tilling your plant produces more plants (and maybe gives a different ratio of plant versus seed).
Result: The majority of players will not see much of a change from now, a few will decide to be farmer and trade time and grind and get more out of the farm and be self-sufficient earlier in the game. "Farmville"-type players will rejoice, everyone else will not be bothered (except players with OCD)
(*) 4 players on a co-op server, none wants to be the farmer. Not a representative sample, just what I see.
