People have been complaining about how League has been going downhill in the last few seasons...
I have been playing League since the beginning of Season 1, and every season there are so many people that say "this is the fall of League" whenever a new champion, idea, or change happens. People complain about how Riven and Vayne are outclassing old champions (which they are), but they are old champions themselves. While it is true that League has fallen victim to mobility creep (Kalista), League is constantly getting better and better imo. Every season, there are states of complete imbalance and states of almost complete balance. Right when cinderhulk got nerfed and before runeglaive, the game was probably as close to balance as could be possible with this many champions and changes. Right now, we are going through a state of almost complete imbalance, because of the Juggernaut reworks, but, yet again, over time, the game will go back to balance after Riot deals with the Juggernauts.
I hate when people say that "season 2 was the best season" or "I wish I could play in season 2 again." Season 1 and 2 both had extreme balance problems, much worse than the balance problems now. Anyone remember release Xin or Le Blanc? Those two still give me nightmares. Anyways, there were so many bugs as well. Poppy could move baron and win the game, anivia could 1v5 penta while in her base (this was in beta tho), you could hold the minion waves with heimer turrets and let loose a gigantic wave of minions that you could push to victory, and so many other bugs. Now, Riot has fixed most of them, except for the occasion knock-up-while-moving bug, where someone gets flown into the air. This has vastly improved the experience of players since that time. People only want to remember the good in season 1 and 2 (don't get me wrong, playing back then was extremely fun), but forget all of the bad. This is just human nature, but just try to remember that every season has had its problems, and every year, League will continue to get better.
and
were both mandatory permabans, at the moment its about 50 times worse than it was then.
