if you considder for example the stats of the old xbow with the new xbow (same goes for the bow btw but 80%) you'll find that the new one has 90% weapon attack, which the old one did not. with the 90% weapon attack you will hit the double ammount of damage from the old upgrade. Same goes for dual swords who have now i think 32% weapon attack. All people who put old duals (without weapon attack) at their noir are probably angry because the current duals are alot better.
