Imagine enemy team is doing Baron... AND you have vision of them (Blue Trinkets, Wards around, Skills from Champs that give Vision... W/e).
They are some levels ahead, or better positioned, so you cant just walk straight, or try steal baron.
**The Mordekaiser can walk up to the Jungler, and isolate him with his "R", when Baron is low!!!**
**Then you jungler can just walk to the Baron, and Smite it. **Enemy Jungler cant Smite (Monsters, Champions, all dissapear, during Morde's "R".
I can see Sick plays.
But it'll take some time, till people master it really.
