Jump spell rework?

It was recently brought to my attention that jump spells create a temporary effect outside of the spell itself. (This explains why I've seen troops jumping past jump spells). However I have also noticed troops hitting a wall where a jump spell clearly should be affecting that section. I think something should be done about this, my solution is simply adding a green aura to troops affected by jump spells, this way players will know exactly what troops are jumpable. It's not a game breaking change or anything, but I believe it would help fix one of the more frustrating aspects of the game. Being the jump spell is so fickle. Thanks for your time :D
