Via Neverwinter's official Twitter account, I was made aware of a survey they are running to get player opinions on their various events. I immediately noticed that the summer festival was missing from their list, and others pointed out that double campaign currencies weren't listed either. I suppose it wouldn't surprise me if Cryptic struggled to keep track of all of their own events, considering how many of them there are!
I gave most of them good ratings actually, I just don't care for things like double glory for example because I pretty much never PvP. Still, when they asked me which events I liked the least, I actually had a hard time choosing and simply picked a couple where based on the name alone I couldn't even remember what they were about and explained this in the comment box: If I can't even remember what it was, it can't have impressed me that much.
I bet everyone's going to vote for more double AD and double refinement weekends! I know I did.
