Just something I picked up, as i never learned the many of the crafting skills until just recently
I hear alot of people complaining about their skill times for mining & teleporting being 10 days+, and though I have BL5, at 60 something skills I have now -- I will finish TPV in less than 6 days without spending any favour on it...
What I think helped me? Not learning the cooking skills. They all still have ridiculously fast learning times (within just 2 hours for most) and will definitely be the last things I learn, as they keep all my other skills in check as far as learning time.
Something to think about for reset & discuss.
