If you were hear season 1-3, it's basically people bitching about how overpowered weak/shitty champions were. Basically crying about how Cho'gath is OP because "I let Cho land his Q on me every time, he's OP!" or "I let Nidalee spear me at max range 100% of the times, she's op!" or "WHy can Akali kill me so fast at 6? WTF? Why are assassins able to assassinate people rito!?" and each time Riot would nerf Irelia.
This was like 90% of the threads on the front page. The other 10% consisted of bad team players complaining about how solo Q is bad and how we need Dynamic Queue-like system (imo you're a better team player if you work well with any stranger rather than just the people you prefer to play with). Trust me, the memes and games is a vast improvement to the salty cancerous haven that was the League boards in the early days.
