Make Ghost less effective on mages and nerf junglers

Ghost makes mages more reliable assassins due to the mobility it gives. Furthermore, it has essentially outclassed every other summoner sans Flash for every mage in the mid lane. Can we either make Ghost melee only or nerf it for ranged champions (e.g. 5 minute CD if the champion is ranged or no moving through units)? Hopefully, this will help assassins not named LeBlanc find a place in the meta.

Also, high elo players and professionals have all pointed out how junglers are franklly a bit OP right now. Could something be done to lessen their influence on the early game, like nerfing/removing the jungle/XP steroid? Advantages in lane are pretty much nullified, which diminishes laning as a skill.
