An idea for the ranked system and the game in general. feedback please

So after playing LoL for almost 3 years now since the beginning of Season 2 I have come across a couple of things and have came up with a couple of ideas that I would love feedback from the comunity and from Riot themselves. This will be quite lengthy, again feedback positive and negative is welcome.

1. I have a couple of friends who play Dota and they explained some of the stuff that they have. An example would be that if someone is DC for example, rage quit or never connected to the game, that the passive gold they would get is redistrubuted to the rest of the team. So instead of the 4 players getting 1 gold per second they would get 1.25 gold per second. This way to help try to make the games still even although it is 4v5 in ranked, normals, and so on.

2. For the Ranked Solo Q and Team 5s, if it is registered that a person never connected to the game, I was thinking something similar to that of Loss Prevented but not entirely. A team shouldn't lose or gain 20 LP becuase someone disconnected or had a problem with the client. So instead, lower the amount of LP lost and gained in these types of games. We have all had them happen on a regular basis and they are not fun. I know for when loss prevented is on the winning team only gets somewhere between 5-10 Lp and I believe this should be implemented for 4v5 games, along with no chance for demotion. Obviously there will be people who rage quit becuase of something that someone did or what not and I have yet to come up with an idea on how to not have people abuse this system if they are losing badly 5v5.

3. Increase the bans to 4 or 5 instead of 3. 3 just simply is not enough, I understand that it is kept to 3 because power picks are power picks in every lane and that teams need to choose accordingly, but as of right now I feel that 3 is not enough. This kind of a personal opinion but there are others who share it im sure.

I hope this list generates some discussion among everyone and even some interaction from Riot as well. Thank you for taking the time to read it!!
