The game needs so much work right now to be fun again.
Lets start with the most least fun aspect of the game right now. It snowballs out of control before the 10 min mark most of the time. How can we fix this? Well first blood gold contributes to this but it has been a core aspect of the game for a long time. First blood on towers also causes games to be snowbally. There are two factors to snowballing games. One being gold and having a significant amount more than your opponents and, two being how easy it is to take down towers and push for objectives. Now a while back riot gave faster gold income to the lowest gold generating ally. We thought this was a good thing because it gave more resources to your support and jungler, but was it?
We as a community have become accustomed to the way the game works and we all seem to like it, however we do not like the games feeling like they are out of our control. Introducing the second main problem that the game has, "Too much damage". Its sort of ironic that this also contributes to the snowballiness of games because it allows people to start doing tons of damage after they build one item which they got from their first blood or first tower gold generation. The game would slow down if we reduced the rediculous amount of damage that champions deal. Every single champion in the game needs to have their damage reduced! This would make games less snowbally and fix the global "damage creep" problem.
The main problem we have now is, how do we do this without having to adjust every single champion in the game? Well for starters we could lower the damage on almost every item in the game as well as lower penetration items. Secondly we could adjust the numbers from runes. Do we really need 20 AP at level 1 with a rune? No! make this like 10 or something. Early game damage also contributes to the snowballyness. Lastly as a last resort kind of thing we could give resistances to every champion. This needs to happen for the health of the game.
