I think its about time to address ghost and exhaust

You know, ghost is far too strong for its low cd so much that even top laners are now starting to abuse this (and it makes certain champs overpowered, like darius for example).

Exhaust is too overloaded and is far too great at both offensive and defensive use, it needs to be tuned into a more niche spell rather than a do it all, theres no reason for it to have armor mr shred and a huge slow (so not only your target cant fight you back, but he cant run away either).
