Hi, I have both SCH and AST on lvl 70, but if I have to choose i prefer playing as SCH rather than AST. SCH just feel right for me, it has lots of micromanaging and could be so powerful in late content if you manage the micromanaging well. AST on the contrary is easier to play, so versatile, and less micromanaging. I play as AST in tougher content when i need to fully concentrate on mechanics such as savages content.
