The popularity list I don't mind. It can be helpful sometimes. And I enjoy watching the trends.
It's the lack of Tier 3 4 5 villagers available for giveaway/sale/trade at any given time. If you really love them but Cycle towns are in a hurry no matter it seems them "valuable" enough that they auto-void.
Or put them up for a giveaway for 10 minutes!
And The VPList has made some people shift perception that Tier 5s are "worthless". There are some great villagers there! They have value!
I got verrrrry lucky once with a Tier 5 trade like that. And then they held them for ransom until I gave money for the "hassle". Lol
But honestly I see the other side too - such unique niche demand! And I had a cycle town last summer. I'd like to be able to help people find their dreamies especially if they are Tier 3 4 5. Logistically it is a challenge.
Villager Popularity List is still necessary right now. And that might change with Amiibo.
