Fewer people playing Ranked games can have other factors, such as balance issues. The que times really aren't that long unless you're in High elo.
Except balance has been a constant issue. Queue times, even on weekends at peak hours have increased... I waited almost ten minutes to get into a normal game the other day and my Normal MMR is mid Gold. Even ARAM queues have increased significantly.
Longer queues and fewer ranked players each of the last three seasons (this is not a new phenomenon) poing to trouble---my friends list has virtually disappeared the last few seasons also. It used to be that I had 200-250 people online at any given time, now it's around 10. That's quite a dropoff. Even people I've added the last couple of seasons aren't playing anymore.
I get it, you're a fan---you don't believe the Titanic can sink, I understand that this is unsettling to you, but I'm trying to point out that there are serious problems that Riot should address and this topic of behavior is definitely one of them.
The New player experience is also complete garbage and if you aren't getting new players then your game will die off eventually.
And yes, you're saying that if Riot doesn't show proof that proves otherwise, that you're correct. I could say that you enjoy fisting horses, and since you haven't shown me any proof that you don't, I guess I'm correct.
Except there's a difference between what I've done and your oh-so-elegant analogy; I've shown objective evidence that there is a decline in the number of active players, you (nor Riot) has shown any evidence that refutes that claim. If one side has evidence and the other side doesn't it's kind of a default win for the guy with the evidence... that's kinda how it works there chief.
You don't see Blizzard running out there and openly publishing their WoW sub numbers like you used to either.. same with any video game company that has a product in decline---really any company in general.
But, hey, keep your head in the sand if you like, some of us actually care enough that we want ot fix the issues that this game/community has.. that's what a real fan does, by the way, not simply being a yes-man for the company.
