Boy, you must HATE Festivult. Having to go walk over to trade in those coins to the Jester each time. He should just auto-take it from your bag each time you get them! Oh, but, he should also give you extra inventory space as well.
And man, those raid rewards, why can't they just auto-turn in? GAWDS, WALKING SUCKS.
Totally with you, but until you find us the secret rocket boots unlock, I think the appropriate response is 'smile and say thanks'.
On the off-chance you just glanced at the offer and didn't attempt it, do note there isn't actually a form to fill out or anything. Assuming you have a social media account of any sort, or are willing to make such, it's literally just two clicks on the offer, and it is completed.
And if they DIDN'T base this through social media, they'd have to build up a full webpage for it, which A: is more work than it's worth, for them, and B: Lets face it, they don't have the best history of (1: DDO offers outside of game being reliable and 2: Creating events that can't be exploited).
Getting upset because they're choosing the safe, easy route- for both them and us- seems a bit contrary to what's best.
