When posts complaining about imbalance get more likes than posts in Memes & Games, it's an issue.
What I mean by this is that if a top-rated post exceeds over 300 likes, it should be immediatly put into consideration.
One example is Zed. I'm sure everyone has either complained or posted about this champion.
Giving an assassin high mobility and large amounts of damage will never be very good. Zed has been in an unhealthy position for around a MONTH. Not a week or so But a month of dealing with that unhealthy champ.
And he's not fun to play against, either. Of course there's champs like Fizz and Leblanc whom can be extremely annoying, but they rely on snowballing to do something useful. And Leblanc is forced to use her harass spells to have decent wave clear, while Zed sits there laughing throwing 2 shurikens that drop Leblanc to 50% (or lower) without risk.
Now, of course unbalance can occur in any game. But not jumping onto the issue for PRACTICALLY 2 MONTHS can be terrible for the playerbase in general.
