Regards with Runes and Their Master Flaw
What we have now and what we can do to improve the underlining issues currently present:
As a player who has made many smurfs and has played many, many, many games with alternative accounts that would probably total at about 20k hours of gameplay. Not to mention, taught many people how to play I have formulated this criticism ever since I started playing this game as a little baby. (I believe 10 is prepubescent and therefore baby...ish)
When I started playing I had a difficult time learning how to play, there was no tutorials or guides on anything since no one knew how to play.(Fun note: it took me at least 4 months to figure out there were items) I didn't really think about it much and as it is I didn't think there was much to learn since I only ever pressed one button to play and then you'd wait.(from my memory, I guess it was more or less muscle memory at that point)
Anyway, avoiding outdated complaints, I will use my experience teaching players how to play league. After teaching them how to do in-game stuff(btw I've requested many times over the years for a good resource for teaching) I always take them out to the next part which I always tell them is one of the hardest things to learn, Runes and Masteries.(Boo) The first thing I hear is either "Why do they cost so much" with added profanities, "why are there so many" with an added sigh or whine, "why does everything have to be so complicated" which I've heard repeatedly from square-one and a variety of other complaints. This is where the majority of them lose their walnuts and full-heartedly consider just giving up on playing.(if they don't give up within the first 10 minutes) Now here's where the good stuff comes in, my request based on what you've already done before...
In season 6 you removed Tier 1 runes and made Tier 2 runes 1 IP, I highly consider you do the same for Tier 3 runes. Now I understand what you might be thinking and all those responses must be along the lines of "The players who have been playing for years and have gotten earned all the runes would have done it for nothing", but you have an opportunity to give them something with the new honor system and that can be debated on with your associates because no one knows what sort of rewards will be available.
Adding to what I said about making them 1 IP, I believe the reasoning behind making it 1 IP instead of just being free was the result of a weird market framework or something that didn't allow you to make it less that 1 IP. Maybe this would be a great time to make something free in the market for the first time!
This community has always had great ideas and I feel like no one can appreciate that more than a member, that's why I request you all to write your opinions and discuss this with your fellow summoners to construct an even bigger picture.
