So I'm cycling my toons to collect their daily scrolls (horrible concept btw), and some get two scrolls and some get one. Similar Ascension levels, similar quantity of scrolls in their bags. At first I thought it was the stupid lore 50 tag, but one toon had 48 and received 2 scrolls to take him to 50, whereas a couple of others had 45 or so and only received one scroll.
For me, each toon got the 1 normal scrolls and, if they had space, then got the 5 bonus for the week. It was consistent across all of my toons. I am one of those weirdos with a spreadsheet, so I know exactly how many each toon had. There was also a message on the toons that were not able to get their 'bonus 5' that they didn't have space for 5 so didn't get them. I expect when I get them down far enough that they can get 6, they will get the 1 plus the bonus 5.
