I haven't really seen a lot of "constructive criticism" about the new HUD, about the Fiora rework, about the AP itemization changes, about the AP jungle item, about the new Cottontail Fizz skin, or any of the other dozens of changes that Riot has been implementing this Season to make improvements on the future of their product. That is exactly what they are doing, though. They are seeing a vision of where they want this game a year down the line, or even 5 years down the line. They are not using short-sightedness to guide their vision into the future. The future for them is far further than the week it'll take for people to adjust to any new changes they make.
I see a lot of crying. I see a lot of "change X suck balls". I see a lot of "such and such is cancer". I see a lot of "Rito ruined the game, I quit". If you go into every decision they make with a knee-jerk, "Oh my god the sky is falling" mentality, you may as well pack up shop and find a different game. That's just like telling the guy in top lane after he's died a second time in 10 minutes "GG, we lose". Everyone talks about the "toxic community" in their games, but these boards aren't any less toxic and counter-productive some days.
Ultimately, this is Riot's product, a product that they want to be successful. They're not making choices within the game to ruin your life. They didn't look at their player base of their FREE TO PLAY game and say "we have too many people playing, let's get rid of a couple hundred thousand by making wholesale changes that will destroy what we built". They genuinely want to build something that lasts and you really have to have more faith in them than that. If you don't have that faith, don't invest your money into their product. If you don't have a belief that these employees want to keep their jobs and improve a great game, keep your money and invest it into something you do believe in.
Change isn't always good, but change is inevitable. Riot isn't ignoring people or dismissing your opinions when they move content from the PBE to live. They have cancelled several ideas that they have had after it hit the test phase and didn't work the way that they wanted it to. But I am willing to bet that as Riot employees, the Reds have been instructed by their bosses to not post anything in regards to new changes and these rampant flame posts that litter the boards. There's no reason to fuel the fire when the answer they give you as to why things change will never be the "Sorry, we'll change it back right away" answer that you all want. Instead, they'd rather let the community flame and attack them while they monitor and assess where they should be putting their resources in making the game better on the whole.
Every day, I look forward to seeing what new and exciting changes Riot has on the horizon for what this game could be. There isn't a single game out there right now that brings as much free content to their community. New champions, new game modes, and new events (like Shurima and Bilgewater) keep the game fresh and still FREE. Yes, they introduce elements of each event that can only be experienced through the purchase of real money, but much of the content you can experience without spending a single cent.
In the end, I have put plenty of money into this game. I have done so with little regret. It's better than spending full value on a game for my console and putting it up to collect dust a month later when I have finished it off. Instead, I have the ability to log in each day, interact with a generally fun community, and put my skills to the test in a very solid game. This is a game that from week to week, I never know what opportunity I might get to enjoy. Next week I might have to re-evaluate my item choices with a patch re-balancing my favorite champion's toolkit. Or maybe I get a chance to try out a new or reworked champion that becomes my new favorite. Maybe I'm just an optimist, but at the end of the day, I would much prefer to embrace the inevitable change of a game that has provided me over two years of challenging gaming fun and will continue to do so for the foreseeable future.
