If there was just one thing, that we had hoped had been learned from Season 8...
...it was that too much change is bad.
This is staggerring.
I could rip this apart, piece-by-piece, pointing out the balancing difficulties. The boards are full of others who will do that.
Broadly, though... this is TOO MUCH. There's too much here that will interact even with the OTHER changes.
In more than one instance, the reason given for the change was "just because" (more-or-less).
This is going to be a disaster. Probably, these things could be done successfully, if slowly and gradually. But dumping the entire mass on pre-season, won't give enough time to recover, even by mid-Season.
We still haven't adjusted to "Runes Reforged". Season 8 was broadly considered to be the Worst Season Ever, and largely because too much was done at once. Considering that certain chaotic mechanics were rolled-back in Season 9, Season 9 may be judged as even worse.
Some of these changes, look attractive. But the game is too complex to allow changes of this scope and scale to be implemented in a pre-Season. ...
You don't need ME to tell you this. I'm really nobody.
And four months from now, it's not even going to matter that I said this here, beforehand.
I just want to play a game that works...
