Losing the "enhance restraint" from Ravager's Mufflers +2 is a devastating blow to those 5hits.
Your 5hit:
41 STR, 26 DEX, 66 Att, 63 Acc, 8% DA.
Current 6hit:
49 STR, 25 DEX, 76 Atk, 48 Acc, 17% DA, 8% Crit. Rate, and the boost from Ravager's Mufflers +2(Extra 1%~ WSDMG per/hit).
Even when restraint is down, the same 6hit has a 6%~ advantage with 8 STR, 8% crit, 9% DA, 10 attack and being able to WS in augmented Heca mitts +1 and a second STR ring. It's even further behind when using a proper restraint down set for 6hit(assuming Acc is capped).
