Creating a battle is vital to completing daily missions. Removing "non-pro players" ability to create battles, puts them at a further disadvantage to pro and premium players. Seems more likely that this is a way to get people to need to play pro. Using ease of use as the reason to justify forcing people to move to pro isa smoke screen. People could use the battle button or create a battle they needed to complete a daily mission. It would have been just as easy to have the battle button route only to standard 15 minute games and still allow non-pro players to create battles. This would allow non-pro players who created battles to "not be interrupted" as the battle button would only route to standard battles and not those created by non-pro players. Now if you want to have to have a battle with just a friend you have to spend crystal and be a "Pro". Great way to get more people spend crystals on "pro battles."
