So here's a thought...
The game is constantly being re-balanced with champions being nerfed and buffed every new patch. I keep hearing that in an older season (I think season 3) the game was much better in terms of balance and therefore more strategic and overall more fun. Even so there were still balance changes in the future and following this trend we've come to the mess of the current season where balance appears to be completely thrown out of the window and most games now end up as one-sided stomps.
Apparently Riot doesn't make balance changes only when champions are truly overpowered/underpowered but also for the sake of keeping the game 'fresh' regardless if in doing so they deviate away from the formula that made the game fun in the first place.
I ask you then, since we can never achieve what we call 'perfect balance'... wouldn't you prefer the game to be changed in a way so that we can reach a meta where at least the majority can agree that the game is 'fun' overall even if balance is still somewhat imperfect and just leave it there?
