Hey man, i'm not sure if this helps but below are my offensive stats. Might help you spot the bigger differences. My high end hits prior to getting shako and evernight is around 200m to 300m. I was using Tuskhelm though instead of godslayer. With tuskhelm on I have 226 max fury. I'm using maxroll hota guide.

I think it's a combination of max fury, crit damage, damage while berserking and overpower.
