Power Creep in league of legends

This is a short summary of how league of legends has evolved since I've been playing:

Ashe used to be considered a broken easy mode champ with too much power for too little skill, who nobody could touch because of her range and permaslow.

Then all kinds of nasty bruisers were invented to kill her.

And then the tank meta happened.

And then RIOT buffed up magic damage hard mages utterly annihilated tanks.

And then Assassins became popular as a way to prevent mages from ever reaching full steam.

And then people realized that tanks don't do anything if both carries are dead, and so Assassins became popular for 2 seasons straight.

And then supports were given tools to peel assassins (and everything else), along with buffs to marksmen summoners and items that made them more difficult to gib.

And then people started playing burst mages (assassin's burstier but less mobile cousins) so that they could continue to gib marksmen.

And then burst mages were all nerfed hard to make that not a thing, with the removal of DFG.

And then tanks were given buffs to make it possible to kill marksmen, especially kalista, and the tank meta happened again.

If history repeats itself, the mage meta is up next. Ryze rework will likely be what starts people thinking about taking mages to deal with tanks again.

#During all this time, power creep.

And today's "Ashe" looks like Kalista.

I bet in 4 years kalista will just be an inferior version of "Vukdulu" because she only has infinite dashes, and he has infinite knock backs
