Kalista's R extreme range

Hello League Bug Forum, I was playing a match recently as a support. The opposing bottom team duo was Kalista and Sion. After a while we all gathered together and started fighting and Sion tanked, but Kalista was out of range on my screen (1080p with reduced GUI), like really far away, and she was able to take Sion safely with no problem and then Sion ran back. If there is a range problem with Kalista's R, then this could be used for the jungler. He could be really far away and essentially teleport from his location to where Kalista is and gank. Even though we won the game I still think this should get looked at a bit.

Thank You League Forum
