The fact that WG does a gambling event instead of an actual sale, it doesn't surprise me anymore. They won't be the first to do it and they won't be the last either.
The thing that disturbs me is that they indeed have (almost) nothing on "sale". As a resident from Belgium, I can't really do anything here due to the gamble laws that remove lootboxes.
I don't mind throwing some money at games, it's my way to help them make new content. I had hoped for even the slightest chance for a ship like Missouri, Musashi or Enterprise.
Think these things through, think about everyone.
