Janna and lulu are still massive problems.

Don't let the nerf make you think that they are now balanced. They simply went from "gamebreaking op" to "very strong". With very and % bonus heal/shield power they can get 500+ shields on 6 second cooldown. This combined with their cc can single handedly make a hypercarry invincible. They also sharply increase the damage output of the hypercarry with . This is also not factoring which can provide 1000 more effective hp for the adc. Those who have played against a combo will know if you don't snowball extremely hard before 15 minutes, you will get steamrolled in midgame to lategame.
