After using the jump potion on a Paladin, I decided that Jak needed other class as I don’t want to go to Lak Shmi as a tank. I am not confident enough for that. So I picked up Astrologian to help heal instead of tank. I know this class pretty well as it is my main healer class. I have also picked up Monk and plan to level that up after I have got Astrologian to level 70.
