Realm Warp: Left Behind

First off, I think the development team and the art team did a fantastic job on the Ryze update, personally I never invested much time in this champion prior to his, re-re-release; however in the game I played earlier with him, I found him to be rather interesting and enjoyed the playstyle of his kit. I suppose we shall see if I still like it when going against Ryze haha!

Anyways, the point of this post is to clarify something about his Ultimate, "Realm Warp".

I had a Jhin on my team and I, as Ryze, used "Realm Warp" on top of Jhin while he was using his ultimate, "Curtain Call". What we both expected to happen was that he would be ported with me to the new location to continue with the team fight. I figured it would cancel the remaining shot on his ulti, but I was ported to the rest of the team to continue the fight, while Jhin got left behind for the remainder of it. I figured this was a bug so I tried it again, I sat back by Jhin, waiting till he used "Curtain Call" again and then stood on top of him using "Realm Warp". Again, I ported to the intended spot and Jhin was left standing alone.

My question is: Is this an intended result, or should he have been teleported with me? If so, what kinds of abilities cause someone to get left out, and would it be possible to add something to the tooltip for clarity purposes so players know who will get left out of the magic carpool?

One last thing has RIOT considered a skin-line themed around modes of "Public Transit" featuring: Tahm Kench, Bard, and Ryze? You've got your Ferry, Subway, and Taxi respectively!
