Excuse me if I'm wrong, but I thought that RoD now gives -10% evasion for mobs, that means that if before RoD you can't miss in t5 with 472 accuracy, now you won't miss with 472*0.9 = 425 accuracy, which means that all the party can now equip new bard-based BiS items with other stats like crit and maybe determination, which will boost their damage. So, instead of making defences 10% better bards now can buff entire party's DPS (self, too, of course)
