The only tea I find worth the time to grow berries for and use/sell, is the ore, wood, and max health tea. The scrap, rads, and health teas, are simply not worth the effort to make at this time for what little utility they provide.
I like the idea of health regeneration tea. That’s really what the health tea ought to be, compared to what it is right now. Also, I’d like a tea that increases your running speed by a certain percentage, depending on the grade of tea, to up maybe 10% increased speed. A universal 30 minutes for ore, wood, max health, regeneration, and speed, seems a fair amount of time for all the work one has to do to make the tea.
Facepunch unfortunately has the habit of putting a new feature in the game, then letting it sit for months or years before touching it again, if ever. It would be great if they’d continue to adjust and work with the tea system, but I’m not counting on it. Ore, wood, and max health tea, is the best we’ll likely have for a very long time.
