It's ok to change old items and add new sets, but make them useful, not only for the sake of updating the game. 90% of the items changed from recent updates are too weak to be used. And hats are OP. Hats used to have (alongside necklaces) the lowest bonus from all clothes. But these updated hats are OP and the other items are too weak. I understand that it would have been a bad idea to update blouses, pants, belts, boots and scarves in the same way, because it would have made the sets (even the new ones) weak and ruin the balance, but I don't think updating other clothes with unnecessary bonuses fix something. Too much time is wasted with this type of updates.
