I'm going to list the options here as it is going to be neater than listing the options above.
Option 1: Retains existing values while also rewarding goalies for OT/SO losses (no tweaking needed to be done to the other stats to retain their balance with skater stats, as the addition of OT/SO losses counteracts SOG & Takeaways).
Option 2: Rewards goalies for regulation wins more than SH/OT wins, while still giving some reward to OT/SO losses (as this change reduces the value of SH/OT wins, GA have been reduced from -0.4 to -0.35 to keep the balance in line with skater categories).
