Contrary to this:
[*] Guaranteed Script drop during first daily for each type of Script (Focus, Signature and Affix) and a 25% chance for repeated dailies in that category
I've been getting a script reliably for the past two days from each type of daily that can drop scripts. IE 1 affix from Undaunted, 1 from West Weald World Boss Daily, and 1 from Cyrodiil Quest Daily, and the same for the other types from their respective sources, for 9 total possible scripts.
Today is the first day I've actively farmed the different sources of the same script so I'm unsure if this is just bizarre RNG or if I'm on to something.
