I'm a sucker for a good bargain. I really enjoyed the crown store sale a few months ago and would love to see something like that again for Black Friday! Maybe even an exclusive mount for the holidays or a package deal (nothing lore breaking please). There is still plenty of time to plan for something like this; it would give players sitting on their crowns something fun to look forward to.
A black Friday sale would be a great way to boost ESO's profits as its a day most people save for and while most gamers go hunting for bargains on newer video games its a safe bet that loyal ESO players would spend a few crowns knowing the prices are to good to pass up.
