Game Suggestions, Ideas, & Feedback

After playing League of Legends for so long, I came up with a few suggestions. I might not see everything in terms of the implications of each suggestion I make given that I am only a user and not a developer of the game. So do bare with me.

Rank Queues: why have a "select your role" option but then have the forced auto-fill only to have people dodge the queue or worse -- play a role they don't main and ruin the game experience for everyone? For ranked, I would rather wait longer and get my main role than wait a minute less and get a role that I will fail and most likely lose the game.

Towers: I understand that towers are equal in durability (health) throughout the map, but that makes little sense when you have champs like Nasus that can take out a tower in a few hits at level 5 while you have Lux taking out the tower in 20+ hits at level 15 (I know it's a bit inaccurate but you get the idea). Or if you don't change the tower durability, then make it hurt more. When Talm Kench can walk past two towers and back again, taking 6 or 7 hits while getting hit by another champ and he still doesn't die (but instead kills me) -- I forget the true point of the towers and just consider it a flimsy and boring objective. Perhaps there is room for improvement there.

AFK: I appreciate the "REMAKE" option when someone doesn't connect. But more often than someone not connecting is people disconnecting sometime during the game whether it is via a bad internet connection or rage quitting (very often). At this disadvantage, the team is for certainly going to lose. Out of probably 100 games where this has happened, I was able to win 2 -- only because the other team was really bad. So why not do this: after someone AFK's for longer than 5 minutes, do not allow him to reconnect but instead provide a slight advantage in gold or lower the death timers for the team with the disadvantage.

Game & Ranked: There are so many people that are horrible at this game. Out of 10 people playing, at least 7 are horrible and 3 are good (not great). Perhaps a better tutorial of the game with in depth exercises is needed before people jump into the game. What this game lacks is a way for people to learn how to improve their game and feel motivated to do so. Additionally, have people reach level 6 mastery with at least two or three champs before joining a ranked game, on top of the purchase of 16 champs. Many people take ranked games seriously and it just ruins the game when people play really poorly. **Further, if I'm 10/1/1 with 300 cs but the team has ADC Fiddlesticks (0/12/2) and Jungle Bard (0/15/1) -- chances of winning the match are very slim. So why am I losing match points (or the same amount of point as everyone else on the team) because of two idiots that decided to troll? Since this game matches random strangers together to play as a team, it is wishful thinking and hoping that everyone will be serious about winning -- and I for one, should not be hurt for something I had no control over. **

Match Grade: I'll be a bit blunt here, but the match grading is pure nonsense. If I'm 8/3/1 with 260 cs and I contributed to taking down 6 towers but I end up getting an "A+" while another teammate took zero objectives but has 8/1/2 with 240 cs and they get "S-"? Perhaps each champ threshold is different, but why aren't objectives considered or weighted more?

Thanks.
