that's an important problem in AO: skills are not balanced. Some are a must for everyone, like nano skills, body dev, treatment, ect... and some are useless, like adventuring, psychology, tutoring, ect. Here some ideas I had:

-Adventuring: now it change your life/nano regeneration, like 1 point for each 5/10 points in adventuring. New stuff requiering adventuring, like usefull backpacks, maybe armor or other stuff...

-Tutoring: new tutoring devices, for all skills exept abilities. They are now usable on other players.

-Psychology: make it a requierment to use tutoring devices on others. New item, requiering psychology, that reduce the chances to be aggroed when used on a monster.

I hope you will like those ideas...
