Kindred's passive shows up on monsters until the 8th mark, which then spawns on Herald, Baron Nashor and Drakes. However if the game pace is rather fast, you won't have 8 marks to then scale more off these monsters. What if Kindred would get a stack from drake, herald or baron even when under 8 marks? Not only would make it a better objective in general but also make it so doing an early drake would be an excelent choice. So in other words, make it so these epic monsters would have a permanent mark on them.
