Without equipping shields, you will get sucker punch as a
passive skill for 1 handed which very handy for crowd control.
However it poses a very high risk, so I want to suggest if its possible to create like an armband or a reinforce form of bracer to be an alternative gear for the offhand slot.
I think it can be slightly weaker than the shield but offer some stats and I hope this will encourage players to try 1 handed with no shield to make use of sucker punch more often.
