Fiddlestick Pathing Bug When Using Ult Near Dragon

If you try and stand behind the dragon pit on Blue Side as fiddle and click his ult he will 50% of the time walk toward dragon pit instead of ulting. This has messed me up many times because I would ping my team that I am about to go in but it would make me "auto walk" to dragon instead of charging his ult.

Please Riot remove the pathing function on his ult. Instead maybe make a noise that lets us know that his ult can't be used there or something.

Thank you,
