maokai, nasus, and cho nerf needed asap

maokai is extremely op right now. that champion heals for 1k to 2k hp every time he procs his passive. that is massively op and mortal reminder and morellonomicon does almost nothing to stop it. needs a nerf asap. nasus is another champion that is very op and needs a nerf asap. heals too much and the cool down to his Q is rediculously way too low so he just spams that Q every 1 to 2 seconds. there are many more champions that need nerfs also but so far these 2 are out of control and need a nerf right away. same thing goes with chogath's ultimate it needs a nerf. he does waaaay too much damage with that ultimate. please do something about this because people are getting undeserved wins cause of these broken champions.
