The spawn rate is down by another minute (to 5 mins) nowadays
On the fungus page Morromid's post reminded me to take up fishing to pass the time so this foraging alt has gained 140 levels (and a lot of fruit, veg and sandals) to ease the tedium. I just swing the camera view around to watch them pop as I'm clicking my foraging and fishing macros. On a different toon I'd also gind a Div spell.
At least with the last couple of patches we can stack a thousand bait / mushrooms
