Ok so rate the mentors like a commendation system for how helpful the advice is, but also add rewards for the mentors who achieve a high rating to encourage them to give the most helpful advice they can. I practically live in this game and have a big knowledge library built up, I can explain how all the systems work in detail, but to be honest it gets tiring answering the same things so many times over the years so I stopped making the effort to maintain the novice network. That and it having a lot of off-topic discussion between mentors when last I checked. Maybe I'm being greedy/lazy asking for rewards for advice; think I'll reactivate NN chat soon and see if anybody needs help.
