If you want a faster game but also reduce snowballing

When you give more farm gold, then missing that gold, because you're dead is going to add up quickly. When you got a lead in the jg, you can farm faster, in lanes, you can pressure them off waves, or even freeze it. Denying tons of gold. That change would probably increase snowballing.

When you give them too much passive gold, then a lead doesn't really add up. It wouldn't last very long either. The lead from kills gets smaller and smaller while the teams of 5 are all getting passive gold together.

A 5 kill lead is pretty big when the team gold is 20k to 15k. But it steady gets smaller. Eventually its at 30k to 25k. 45k to 40k.

You get the point. It isn't just you getting passive gold, its the entire team.

It reminded me of this game. https://www.youtube.com/watch?v=oAlUz5pFT18

A team needs to be able to get behind, or rather, the better playing team/comp needs to be able to get ahead. when you increase passive gold, it lessens the impact of the gold towers give, drag, baron, inhibs, 1st blood, tower gold, tf passive, killing wards, draven passive, support items, and the minions themselves. Basically it lessens the skill gap.

Theres also early game and late game champs. You would also have to think about that re-balancing those champs.

It isn't a simple fix, and its arguable if its even an issue when you look at different levels of play.
