The way to make the game less snowball
Tweak kills & objectives
If we can turn kills, mostly shutdowns, into a better anti snowball tool that would be great
Currently getting a kill net's too many advantages imho
You stop the enemy from gaining XP & gold & map/objective pressure
While you yourself still get to grab XP & gold and get the opportunity to push for objectives. On top of that you get kill gold and XP
Even if kill gold and XP are taken away it would still be very worth it to kill the enemy because you can still get gold and XP from cs while they cannot. and you created an opportunity to damage/takedown an objective.
If objectives got stronger, let's take turrets, then this would make them harder to grab and thus more valuable to takedown and in such a way would increase the value of killing an enemy indirectly as well.
If kills did not grant much gold and XP by default but instead the value of your takedown depended on your own amount of takedowns/cs/objective damage etc since the last time you died
Then you would create a situation where getting a kill would not really just snowball you then and there through giving XP and Gold out the ass but rather it would grant you the opportunity to gain advantages in CS and objectives which are now worth more since they are tougher to take
Gain enough of these kills and leads in cs and objectivesyour takedown value would go up significantly which makes taking down these objectives or putting pressure more risky as your enemy will be able to get back into the game by taking you down
I would require more effort to snowball and it would be more risky to keep it rolling as your gold and XP leads would not gain such a massive disparity so while you have an advantage part of it would come from having more objectives. Like a tower to retreat to and being a little stronger from items making it easier to defend.
But pushing your lead would put you at risk since you yourself now became an objective for the enemy team to takedown and gain back a decent amount of XP and gold.
This way league would become a little more objective and risk vs reward focused and would require more strategy rather then getting first blood and roflstomping to the enemy nexus in 10 minutes
