Things to be added to scoring
With the games being quicker and even quite a few being low scoring there should be some sort of mechanic that awards players for going deathless. Basically if there are only like 8 kills in a game total, there should be some boon that rewards the players that play well enough to go without getting killed. Don't make it gamebreaking just a couple points to offer a bit to players that play well just might not be in games that get a ton of kills.
