stopped reading there. this has never been and never will be true.
also this guy apparently never played back when AOE comps were all the rage. I remember back in late 2010 early 2011 Galio and Amumu were considered two of the most broken champions. If the enemy team had one of them you basically had to pick up janna. Oh and lets not also forget when kennen was recently one of the top champs.
Honestly the tornado Q knock up nerf in my opinion kinda did it for me. I think it is minor and actually made it so a perfect tornado can knock them up longer than the old maximum [by I think .1 seconds lol] but that one was the one that really bummed me out personally. To no longer get those quick tornados for full knock up just makes me sad.
Not that you shouldn't plan out your tornados. BUt the nerf to the quick ones really was =(
It is just the little nerfs here and there and people favoring aggressive lanes that hurt her so much.
I think janna still is good, but honestly why pick her over lulu?
Worst comes to worst you max shield as lulu and you are pretty much janna anyway with your cc just a bit different. Or if things are going well you can be incredibly aggressive .
Heck even soraka can totally harass a lane down harder than many supports while still keeping their AD alive and well.
