Enemy Jhin's W indicator shows blue in both team

http://imgur.com/4MBQx0m I just played Legend of Poro King as mirrored Jhin match. I just notice both Jhin shows blue indicator with his W. Its very annoying when i try to dodge every W even my mate's skill, because i dont know who shoot that skill. But when enemy Jhin uses his ultimate, the indicator is red instead.
