At first, I assumed that the daily seals were something given as a bonus. It wasn’t a great number of seals; definitely worse than the daily gold reward but I figured it was probably nerfed to a couple seals a day to balance the new calendar rewards. Or at least, I thought that was the case. Until I went to claim my seals and happened to notice my seals count was 16/1500 for the start of this week.
Which means, all this time the daily seals have been a penalty, not a reward. Since the earned seals subtract from the maximum number of seals you can make in a week, the later in the week you finish collecting 1500 seals the fewer bonus seals you earn for the week.
In order for the “daily reward” of seals to actually be a reward, you either need to never reach 1500 seals by the end of the week, which means you don’t care about earning seals in the first place, or you need to max out your seals on Monday, by winning roughly 140 PVP matches in one day. (4 points for PVP, 5 points for battle won, 15 points per tier increase, and 10+daily reward for logging in).
If neither of these apply to you, then what we have is instead a daily PENALTY to the number of weekly seals you can earn. Each day you don’t hit and redeem 1500 seals means you effectively “miss” the daily seal reward for that day. In order to actually act as a bonus, I believe these seals should not count towards the weekly seal cap.
