Riot, many years have passed... [Sandbox]
...and we still don't have a sand box mode, option or adaptation.
There is no problem to monetize it if it's the problem. You can ask 500 ip for each 1 hour of use, it's fine to me, but it's really painful to create a custom game and spend 2 or 3 hours every single day just because the game value the experience with friends but have no support or attention to the solo training experience necessary to achieve high performance.
This is a summary of what i am talking about: When training as riven i need to manually remove all my runes and masteries so jungle monsters and minions can last longer. I need to farm until level 3 alone also otherwise i don't have the skills i need to train. I need to farm until have a decent amount of defense otherwise i will die in the jungle. I need to have a friend or bot in the other team otherwise the minions will GG without my will. I need to wait my cooldowns, even knowing there is no actual game happening or reason for it to exist. I need to spend a lot of time walking at a very slow speed across the entire map and waste a precious time to achieve some points. In order to train my flash combos, i literally need try it once each 5 minutes. In order to test mechanics around herald i need to suffer even more, as each time baron spawn i need to reset the entire game. In order to test mechanics around baron i need to wait until he spawns. And much more.
My only question is: Why?
Why us, that pass through this absurd undeserving ritual, need to experience this? What is fun about this? What the player experience team talk or think about this?
Back in the day i played support buying 10 wards. You guys understood that was a bad experience to the player and provided us with new itens and a trinket system. It was a decision made to enchant player experience and, therefore, successful.
Back in the day i played against assassins that could also silence. You guys understood that was a bad experience to the player and provided us with new assassin kits, reworks and options. It was a decision made to enchant player experience and, therefore, successful.
Back in the day i played with a very old karthus that couldn't make me feel like part of the league of legends high quality universe. You guys understood that this could be improved and decided to provide us with a brand new karthus, completely cosmetically remade. It was a decision made to enchant player experience and, therefore, successful.
Back in the day our "welcome league of legends window" had just mostly a play button and very litte to offer. You guys understood that this could be improved and decided to provide us with a new one with lots of organized content. It was a decision made to enchant player experience and, therefore, successful.
Very recently i experienced a SoloQ dodge because of a missing sound or window change that made me lose some PDL. You guys understood that this was a bad experience and decided to improve it to a more functional system of alert that we hopefully will solve the problem. It was a decision made to enchant player experience and, therefore, it will be successful.
Then i question you, as this list could go forever, what's so wrong [or good in your opinion] with the solo training experience, that we have to endure painfully, that make no suggestion or argument reach one of you guys? Something that could, once more, enchant the player experience.
I wanted a serious answer about this subject and would be glad if the below points could be in consideration:
1- There are already a vast community that need to endure that and will forever exist as long as high skill champions exist. 2- Some players don't use it often,but used at a certain moment of their lifes. 3- Time is a valuable resource and people spend time they could be using in matches for pointless limitations in training. 4- There is no need to hard coding or hard graphic changes to implement many suggestions.
My personal suggestion to start the post? Add a bunch of 1 gold itens to personalized matches that can be voted to open. Each one give things like: 99% cooldown reduction, 10000 armor, etc. Already would be very nice.
Thanks for the attention. Signed: 

and much more.
