Whilst reluctantly, coz I'm thf and getting nerfed, these changes do seem to broadly make sense, I can't help feeling that twf isn't getting much by way of balance at all here. Those defensive benefits seem a bit meh to me.
I think an opportunity has been missed to compensate TWF by increasing the value of its inherent versatility advantage.
Having a line akin to strikethrough where progressively offhand weapon procs and features proc for both main and offhand strikes and 100% offhand hits can be attained would enable twf to be far more competitive and present interesting choices compared to the somewhat reductive and crude balancing attempt around dps.
TWF needs a rethink imo.
