Reducing the skill requirement is a pretty good idea, however I think that this mythic was not exactly deserving of a nerf.
I propose turning it into:
50%=3
30%=5
This way it does not remove the skill component, where keeping your mag low is essential, but it also does not punish the less skilled or new users of this mythic too hard.
This PTS has been full of pretty good changes, I'm pretty happy, this one is the only one I really disagree with and even then, only partially.
I was also thinking of a linear ramping system where below:
50%=3
40%=4
30%= 5
20%=6
10%=7
however I feel this might be too overpowered to be honest haha.
Either way, the overall nerf is a bit unneccesary but it can be rolled back without taking away the accessibility component you guys have added in.
