Have Fiddlesticks' E go on 50% cooldown when it only damages monsters.
Fiddlesticks was hurt by these jungle changes more than any other champion in the game. Clearing Kruggs or Raptors with him is a nightmare, and his buff clear speed was also lowered with no targets for his E to bounce off of. He's a farming jungler that can't efficiently farm the jungle, he simply needs help.
So have his E go on a reduced cooldown when it only damages monsters. EX: Rank 1 E hits Kruggs only, it goes on a 7.5 second cooldown instead of 15. This would help his damage against mob camps enough that he might not even need any other buffs.
Most importantly, this wouldn't affect his damage or cooldowns against champions, so his ganks and teamfighting would be untouched.
