I feel that. I really do. But I also LOVED the Avatar crossover. To be fair, I haven't played any other ones, but this one played so well and seemed to be very well thought out. They really did the IP justice.

It's also probably worth pointing out that Lego was nearing bankruptcy and was saved by a ton of licensing (and Ninjago, to be fair). Fortunately, they've used that income stream to still consistently put out a lot of high quality first party sets. Hopefully WotC doesn't lose sight...
