I feel ZoS not only created a grindy system that is just frustrating players, but they also missed an opportunity to make it more interesting, and make it grow with your character.
By restricting the drop of Regulus, Heartwood, and all new items to the harvesting process, you are forcing people out into the world. Which is good, and desirable, but it gives the players that want furniture almost no choice.
If the new crafting materials were obtained by refining raw materials, you'd get a bunch of pros.
1. Every raw material in guild stores will become a source of materials. You don't have to wait weeks or month for people to post them at good prices, they're already there.
2. You lock the price of the new materials to depend on the price of raw material, rather than on just their rarity. Right now, it feels too random to pinpoint a fair price.
3. Gives players the choice of farming or buying.
And more importantly
4. Your chance of getting the new materials would increase as you spend skill points on crafting passives.
(I know some will ask what to do for Provisioning/Alchemy/Enchanting. Honestly, I'm not sure. So the solution I'd propose is to leave those three as they are. You will likely craft more wooden furniture than an enchanting praxis, anyway)
Housing is a progression system, I get that. You're supposed to start with an inn room, a bedroll and a candle, and slowly upgrade to better things. But I think this change would make the system become easier over time, rather than always having the same grind, regardless of level.
Thoughts?
