Hmm...I hate to admit this, but i believe Dynamic Q is the official ending of leagues "glory days"
I know this is common complaint, but hear me out. I truly believe dynamic Q is the death of PASSIONATE side of the game. I know many, including my self, that just don't take rank titles as serious anymore. Before if i saw someone was plat 1, d3, d1, masters, etc. I would be like "Okay this guy could be good, or decent". Now...When i see peoples tiers, i could care less, because i can't tell if they're actually gonna be good, or bad compared to their current rating because this new system is awful. (atm i am having a better time seeing someones current skill level, by using their s5 rank, and not s6)
But as i said...I believe dynamic Q is the death of the passionate player base, not the masses. Is league dying? No not at all, its not going anywhere for a loooong time, and its still going to make huge $$$ for a loooooong time. So IMO, i don't think the game its self is anywhere near close to being dead. But i do think riot will be losing most of their passionate (and sadly, that is a small part of their player base in the grand scheme of things) if they don't bring back solo Q, or make some great changes where rank feels accurate, a true test of skill as a player, and rewarding.
Riot please. As someone who has supported your game since closed beta. Please...PLEASE bring back solo Q, or make a new system that actually feels fun, and rewarding on a competitive level :(
