LF MI dependant builds

I’m looking for builds that heavily rely on (or at least have BiS) MIs. The reason is I’ve gotten a char up that I am comfortable farming with and I want to know the possibilities. I haven’t played enough to know all the MIs myself yet and I haven’t seen any standout ones like TQ had. So basically I’m looking for longish term project build(s) that I can work towards other than the straight legendary farming I’ve been doing.
