Double the loot + half the RNG?
I don't have any empirical data to support this but the drop rate for motifs and patterns seems to be absurdly low for this event. It wouldn't surprise me if ZOS double the drop rate during the event but drastically turned down the chance to get any worthwhile loot.
Since the event began, I've killed about 350 dragons in Southern Els and have gotten zero purple crafting plans. I've done the dragon daily quest 25 times and have gotten one Dragonguard motif. This is far lower than the drop rate I saw in Northern Els when there was no event going on.
Probably just me but seems too extreme to be random.
