While I generally do like the idea of a 5 piece accessory set bonus, please refrain from implementing it. Atm taking the second ring and earring from the golden dexterity set outperforms 2x aoth for chain gear and some people (including myself) have already finished those items.
If you consider this change, please give said players the chance to change them accordingly via support. Yes, we were told to reconsider decisions regarding our gear during class balancing, but I think it's fair to say that this statement doesn't apply to changes regarding items.
That concern is fairly easy to address in my opinion if 5 item set bonus will be based on any 5 golden pieces - that way 3 dex and 2 str would give bonus just like 5 str would - so for melee accessories just have 5 items that can be picked from either dex or str sets - and extra bonus for 5 items could just have plain pa and crit, instead of str or dex - that way would be uniform and work for all including those who already made 2 dex and 3 str
No it wouldnt. You miss, that the dex ring has dex on it and the str ring has str on it. That makes a difference at all and you cannot make a 5 piece bonus, that would be same for 3/2 users and 5 pieces users.
Anyway like Serenadae said. Even the golden 2 dex pieces outperform the older str DN versions
