Was playing an ARAM game and multiple times I was attempting to shift to spider form to immediately rappel and it was extremely faulty. Maybe once or twice it would rappel me immediately but other times took me spamming e multiple times before it worked. Of course doing that made me fall to where my cursor was instead of allowing me to make appropriate plays with the skill. Thank you for looking in to this.
I think the faulty portion of it is merely when Rappel casts from outside her Rappel range. Normally it would follow the target until in range, but for whatever reason, suddenly she doesn't cast it once in range now. Tested in a custom game; didn't Rappel a single time when casted outside Rappel's immediate range. Instead she gets in range and completely stops.
OP's problem is likely this, as recasting it once in range will work. If the target is running away, however, it may 'feel' like you have to cast it multiple times since the target never does consistently stay in Rappel's range, thanks to her complete stop.
