Kled bugged? (All other threads combined)

I am not sure if this is intended in Kleds design, or if these are actual bugs. One thing i've noticed personally is Kled with Skaarl and Kled without Skaarl is coded as two separate champions. When Kled with Skaarl has turret aggro and Skaarl dies, the tower changes aggro because it "killed the champion". Another thing is damage given to Kled with Skaarl that causes Skaarl to die, does not transfer to Kled after Skaarl dies. Example i've noticed specifically is if Darius ults Kled with Skaarl with them at an HP that should kill Kled, it doesn't. It kills Skaarl leaving Kled at the hp he was at personally with any bleed stacks he may have ticking. This isn't the case for just Darius tho. I've come across many times where Kled with Skaarl should have died, he doesn't as the damage doesn't transfer to Kled without Skaarl. As I said earlier, I am not sure if this is intended or if this is a bug.
