His current problems:

-Mystery deserves some changes to be more than ''second standart''

-Shield passive deserves a treatment similar to Iruka(which I will suggest)

-Chase is meaningless in a meta where Debuff Immunity is everywhere.

Aim of my suggestions:

-A mystery for different benefits in different situations

-Higher sustain power and survival potential

-Better and more sensible shields

-Chase with options to choose between
