people won't like them and then proceed to buy the new ones.
Explains why Kha'zix and Syndra are bad.
Any new champion I've seen that came out that was too powerful got nerfed.
Even the supposed 'OP' league champs...
Ezreal gets called OP, yet only sitting at a 52.48% win rate.
Even for NA Platnum rank, he's only got a 52.27% win rate.
Yet we see him in about half the games played, just because people think he's overpowered.
Oh how I see people scream in draft "BAN MORG NOW!"
In the past 3 weeks, never broke 50% win rate. Whenever I see people play her they do terrible.
Her win rate in NA Plat is spiking from 30% to 55%.
These are some of the older champions, let's take a look at these so called "new op champs for $$$$"
Elise, the newest champion, has only a 39.34% win rate. omg so op
Kha'zix sits at about 45% win rate.
Syndra at 41.84%.
Rengar, who was considered actually OP and is the 4th newest champion, was nerfed on the 24th. Prepatch, he sat at about 52% win rate, postpatch, he's at about 45%.
But yet Amumu, old as balls champion, is about an average 55% win rate.
Another old champion, Evelynn, before nerfed on the 24th, ranged between 56% and 57% win rate.
Even Teemo, who is considered horribly underpowered by 20 paragraph rants, still has above 50% win rate.
So I'm not sure where you're pulling this "they nerf old guys to make people buy new guys" from.
