Tip for Ruin dependent players during rank reset
Don't run Ruin. If you aren't very good at pressuring the map and pressuring survivors into making mistakes now is the time to learn.
I see so many killers running Ruin vs new players who are completely useless vs Ruin due to not knowing where totems are / unable to do skill checks. This allows killers to have 15min games while under no pressure
These killers then rank up and run into survivors who aren't effected by Ruin and complain the game is broken since they have had no experience pressuring the map.
TLDR: l2p without Ruin at non red ranks atleast
