Punch looks stupid as hell. But you kind of have to take it since there are only 4 st melee attacks in the set, and one is worse than boxing, and the other has a 25 sec recharge
Often when discussing a set with some problems, someone proposes making a copy of the set with a couple changes, under a new name, while also keeping the current set.
That's what we got with Regen.
So if you want the fixed version, play Willpower.
Id halve the bonus, remove all crashes. This would put it more inline with followup.
Then Double the recharge on jab, punch, and haymaker, with the resulting increases in damage.
Swap footstomp with KOB in progression. Maybe move a couple others around
This would bring SS more in line with other sets, reduce the godliness of FS with double rage. But rage would still be a sweet bonus.
