Might be just a bad impression ... but i've been farming Matron Chest in EE Rusted Blades and with +2 loot jewel and Dragonmark of Finding i've been looting NO level 25 items. This morning i've done EE Tide Turns twice and in all the chests not a single level 25 drop.
I think something is wrong with the chests drops level i used to find level 25 stuff with jewel + dragonmark even without the +2 loot event. Or maybe they bugged the dragonmark cannot tell exactely.
Did you guys have the same impression as me or i'm just having a misjudgement?
