Making the game friendlier to new players
I wanted to see if we could all contribute some ideas for how to fix League's steep entry wall so that new players who look at the game don't say "I start with no champs or runes and at level 0? No thanks"
Make the 450 IP champs free for everybody and remove them from the rotation.
Keep the leveling system but remove the "masteries and runes unlocked as you level" part. This way you still have to be 30 to play ranked but you have had 30 levels of experience with a decent roster of champs and you have played with full masteries long enough to understand which ones to take.
Remove tier 1 and tier 2 runes. Tier 3 runes are available starting at level 1. Either reduce their price to Tier 1 prices or remove their price and people have them available at all times.
Have a "higher level" tutorial that unlocks around level 20 that actually explains lane dynamics, like "basic attacking your opponent makes his minions focus you and your minions just keep attacking, pushing the lane" and "how to itemize" (the thornmail part of the tutorial just doesn't work). Even have a "not getting hit by skillshots" tutorial that explains that Blitz can't hook through minions but Lux can still snare through them, to actually help people grasp the game.
People go into a game on a champ and maybe have never watched anything about that champ and just have the "recommended items" to go by. I recommend that more information is available about a champ in client before the game including: Scaling, Itemization that works, better defined weaknesses and strengths (Wukong's weakness section used to mention oracles despite that he can dash from outside the range of it). This is so people can actually understand something about their champ before they go into game. Also the "videos" of the skills at work should be updated and have a "higher play" portion to them, like showing how to navigate walls with Nidalee's pounce or using wards to hop behind people with Lee Sin/Katarina.
Lower the IP cost of all champs by around 10%-15%. This is to account for all the 1450 champs being free so it's not a huge leap to unlock new champs.
Actually release some more "new player friendly" champs (at relative prices, like you've promised before). It might take 2-4 months to design, balance and test a champion like Zed or Kha'Zix but how hard is it to design a Garen or a Nunu?
Active bot tips. We have loading screen tips but why not tips that pop up on screen during bots matches? You know the "quest" system on dominion? Something like that to advise new players how to advance. "Oh, you're dying a lot to Ashe, here is a circle that shows her auto attack range" or "Nunu's ultimate deals a lot of damage when he manages to fully channel it. Use a stun/displacement/silence to cancel a Nunu ult!" They don't even need to have a tangible reward, learning how to handle a situation like that would be great. The same tips could pop up near jungle camps in bot matches. Maybe after taking Mid/Bot tower your team gets a mission to "Slay the Dragon! Bottom and mid tower has fallen and you are all leveled enough to take on this beast! Slay it for it's gold and experience!". Same thing with Baron. These would be bots only features, though.
Feel free to post your own ideas here.
Now for a section of just fun improvements!
Border Accolades. I know I'm going to receive criticism for this one (since I'm pretty much lifting the idea from CoD) but why not a way to customize your border for the loading screen? If I'm playing a champ I enjoy why not have it list my games played with that champ? Maybe my kills and my assists with them? We already have this kind of implemented with summoner icons being able to customize, why not expand on that? I want to unlock a Ravenous Hydra icon because I've farmed up 2k minions over the course of 20 games with a Ravenous Hydra in my inventory. I want to be able to use Warwick's ingame splash art (the little square in game) as a summoner icon because I have 100+ games won with him.
I also had an idea for another fun game mode. Reverse mode! Champion scaling is reversed. Scale with AP? Scale with AD. Scale with Health? Scale with Mana. Scale with Armor? Scale with MR!
Please, commit some ideas, it took a bit to type all this out in a legible fashion :P
