I have received 3-4 scrolls in under 100 total kills farming echronoscope. I saw three scrolls drop for the same person (in a full group of 12) in under 50 kills in the raid.
I completed the entire new chain on epic, with two scrolls drop (both in the second quest) for the group.
You need a LOT more data before you can claim scroll drop rates are actually higher.
Oh, and not a single seal for our entire group. I pulled a shard of the envenomed blade in the chest behind the barrier of the optional fight in Servants. Someone else pulled a shard of (I think) bulwark in the non-epic end chest of Spinner. No named items or shards/seals in the epic chest for anyone, any of the three quests.
On topic, some of the new items are actually pretty nice. Nothing that I want, however. Maybe eventually I will use some of them.
