@Riot - Champion Mastery & Premades.
I would just like to make two suggestions. These suggestions come from a player with two accounts and over 3,500 games played, so I have an understanding of the game quite in depth.
- Champion Mastery & Ranked:
Please place a requirement on ranked games that prevents a player from playing a champion they do not have a mastery of 3-5 for. I say this because all too often I am playing ranked and end up on a team with 1-2 players that have played the champ fewer than 3 times in normals and as a result can't aim skill shots, have to ask for a build of items, need to ask for combos (such as Alistar, Vel'Koz combos and more.) Which ultimately results in a loss as it is a 4v5 or worse - 4v6 game. This implementation would at least show that players in ranked know how to play that champ.
Now, I know some people will say - "Once you get higher rank you won't have that." That's fine and dandy, but it makes the grind to get to that point near unbearable.
- Please allow an option to opt out of having premades on a player's team. This means that if selected, a given player will now have people queued together on their team, but can still fight them. I suggest this because having a bottom lane duo give up because they don't like a player's pick, and then feed the other team, or just AFK. I've also been on teams that have 4 people queue together and do nothing but be massive jerks for the hell of it. Why? Because if 1 person reports, nothing happens.
