I have purchased several of the official adventures here on Roll20 and here is one thing that I feel could be fixed to make a much better game experience. The player handouts for creatures are an awesome tool to show the players what the monster they are playing looks like. However in the official modules it seems all the images are just scans from the Monster Manual. Now, the big issue I have is that all of them have the name of the creature included in the screenshot. I feel this really takes away from the game for my players. Sure, there are some players out there that can name almost every monster by sight, recall most of the stats and special ways to fight them but most players can't. Most players would come across a rust monster and simply by sight think its some jacked up giant insect. But if they see the name "Rust Monster" on the image that takes away a lot of mystery for them.
