Lemon,
to your question as to how much I spend, I've spent between 60-80 dollars in the little less than year that I've been playing. so a pretty low spender. As to your question about polls and such no, but I've read a lot of posts here, and I have watched most videos most youtubers have posted in the time I've played and read a fair number of the comments on said videos. So while I don't claim to know all their thoughts and feelings I do feel I have a decent understanding of the general mindset of the community.
To your first point, I don't want to make a small book so, we are given two bad choices in your current stance. Either save resources that could be used better if we know what champs are used, or use resources and potentially get rid of things we need but dont know we need. It is each persons choice, but with more knowledge people can make a more intelligent choice.
Second point this is still a heavily RNG game and most people even stockpiling wont get everything they need, and I'm not even talking about free to to play. Yes it is better for them, but it is actually statistically better for everyone, because someone just spent (probably) over $5,000 in one weekend for hegemon. People will continue spending. and giving them more notice for double rates will cause them to spend more not less. This is basic business.
3rd. once again this is useful for free to play, but I'm talking about making it easier for free to play and for lower spenders so that they make the game more interesting for heavier spenders which is good for the company. All of these changes are better for every stage of the cycle, FTP, lower spenders, heavy spenders, and the company.
and Lastly I have spent a lot of time in forums, watching youtubers and reading comments. I don't know much for a fact, but I do feel like I have just as good of a claim for reading into peoples comments and words as you do for claiming crying like a baby which I have actually never seen or heard someone actually crying so I do wish that if you are going to claim that I don't know something for a fact and then continuing to use hyperbole. Anyway hope this has given you more insight, but if not I have spent more time than I care to and more space on the forum than I like for such long responses. So feel free to respond if you wish, but either way hope you have a great weekend.
