So, Just before we discuss about Balance(Map balance, Killer power, perk balance)
Soooo... we are discussing tones of balancing stuff such things. But what means balance really critical, is The Skill Based Match making system. Not current Rank matching system.
The point is, Why do we have Plenty of advantageous in SWF? Not only voice chat(information Sharing), they are more likely to play efficiently than solo Q players. That means they diligent to gen, not lazy like normal solo Q.
And also they are more likely to have some more skill. so this is my gut, but they are not braindead like normal solo survivors.
So the point is, Before we talk about balancing, we need to reform Rank matching system. It is totally meaningless, and red rank doesn't promise us he is not braindead. So what make the kill rate so high up to 60%? Thats because asymmetric Rank-emblem system. So if you get avrg 2 kill per game, you will never go up to red rank in killer, but you could go up red rank avrg 70% death rate in survivor. That also means braindead could go up red rank, and make other real skilled red rank survs frustrated.
This bring all frustration with solo Q survivors, not only easy potato, throwing all pallets away, etc. But on the other hand, killers in red rank go through some though emblem-rank system to come up to red rank, So this means they are more skillful than easy braindead survivors.
So it ends up always blaming braindead teammates, when you get sacrifice. yes, IKR. if you are good, you are more likely to escape, but, current games are more likely to depend on not your skill, but on your teams.
SHORTLY: Before balance discuss, we need to reform Rank matchmaking system. Or make survivor more tough than now and emblem system more depends on skill. Or, relieve killer emblem that makes braindead killers could go up red rank just like current survivors' rank system, and make stuff mess up and more meaningless rank.
