for me:
1. just make all the gl maintenance skills be under only one single skill instead of the 4 we have(and if posible, said skill freezes it whit not need of stand still)
2. they should expand greatly what we can do whit chakra, because atm is a total joke(if posible as ogcds)
3. remove the RNG from chakra generation
4. there should be 14 chakras(7 of light 7 of darkness) to use on chakra skills so the job gets some kind of complexity
