I am currently headed towards Majorplayer's feeling with Botania, I had edited my mystical flower withering a little longer time in Regrowth and after updating Botania (mostly to get rid of the nagging update message) but notice that the flowers are withering regardless of anytime you set, checked the config and it's gone, no longer can modify it at all now it appears. It's sad really, great mod but different modpacks give you different situations and a config that you can modify to fit in modpacks is needed. but now sigh...
I absolutely loathe the withering mechanic. It's sad that Vazkii removed the config as I refuse to play Botania with withering passives turned on. It's extremely irritating as passives are generally low tier early play stuff and having recraft them all the time is a pain.
