Community balancing, screaming at riot won't help you.
Most of the boards posts are Nerf Nidalee! She does her job right! and has the average mobility of every other assassin with close to the same damage! Don't even get me started on the Veiger isn't even playable anymore! Because we all know you can still blow up AP- Carries and stun the entire team during team fights.
Basically what I'm trying to say is, most of the reasons you have for nerfing/buffing are well, not that good, as well as the fact that you probably know nothing about balance. Nerfing or buffing champions aren't how you balance correctly, there is a fine meta to these changes that Riot has to consider.
So please, put some deeper thinking into your salty-spatoon complaints.
