[...] the format as it has always existed to this point has been erased.

You'll be the salty one when you have no one to play with when everyone is sick of buying all the new modern horizons mythics erasing the things they actually liked about the game, moron.

As it always has existed? Where's Hypergenesis? Where's Shoal Infect? Where's Pod? Where's Twin? Where's KCI?
Modern has never been "stable". It has rotated plenty of times, by standard sets (even before WAR), sometimes multiple times in a year and it almost always was very expensive. And then we had bans that also "rotated" Modern.

So, for all your complains, you seem to forget the format's history.
