The game will allways be harder for new players, It will be really hard to change that
In any player vs player that has any sort of progression it will allways be harder to make it easy for new players, specially when the game contains soo many perks a new player has to learn about
The best options you can give a new player is either
-Make a better tutorial
-Make the grind easier for new players
But please don't change powers and perks to accomodate new players
Decisive strike can be seen as unforgiving for new killers, but it still remains the same, while ruin got changed.

Who uses ruin in rank 20 anyways?
specially conssidering that the rank is locked 15, and I doubt any killer will be able to get ruin teachable before they reach rank 15
