I would like to propose a suggestion for the now updated shield bash feat. Now that it allows the base 20% Two weapon fighting property that every character gets whether they have the TWF feat or not, is there any way to update the code (and game) to include TWF feats in the computations for percentage chance of doing offhand swing? I would like to cite that you can do such things in the Pen and Paper version of D&D and although DDO is not Pen and Paper it should translate easily.
That being said I do not believe it would be a broken power surge as shields are not optimal weapons at all for one. They should also count as a medium sized weapon (not light in any aspect other then maybe small shield). Regular TWF and THF melee would still do significantly more DPS but a specialized sword and board melee could optimize his setup for offense/defense.
Thank you for your time.
