about upcoming Janna shield nerfs
Riot if you want janna to start playing interactively, giving 18 second cd on her shield is not the right direction.
if it feels that her shield uptime is ridiculous, then why not nerf shield duration early game instead? Right now her shield lasts 5 seconds, and that is certainly very unhealthy when trying to look for good engage opportunities early game at 10 second cooldown (9 sec cd if u count masteries cdr and coin cdr) http://leagueoflegends.wikia.com/wiki/Janna
Reduce that ridiculous number early game based on skill level. Example: change the shield duration from 5/5/5/5/5 seconds to 2/2.5/3/3.5/4 seconds (again, this is just an example to show what i mean, and numbers are in no way final)
This would encourage janna players to poke more than increasing shield cooldown.
