On topic:
We have a freaking Shop Content Manager? Are we sure that is not a clever bot pretending to be a person, while running "assign weekend_sale = random(Sale_Choices_List)" script?
Oh, wait, that was off topic. Ok, on topic:
ABLs at 50% were welcome sight. Daily Resets always good. Mega sales, as much as I personally hate them, are often a hit. Minor consumables, like transport runes or charges, are good. Occasional rare item that few people want/need but would buy on good discount, such as costume, mount, wings, etc. Obviously, items that are in demand but rarely seen, *cough, cough* +16 jewels, are great. Maybe mount speed potions.
The things I would like to see less are XP/TP charms. Yes, they are useful, but even at 50% off they are too expensive, especially since they top at 1 million, and that is a very small amount these days.
