I set up a friend on Bluestacks, and it has some SERIOUS limitations. 1. Can't rotate your island 2. Can't join a guild, except those on the recommended screen (or one that's either on the leaderboard, or has a player on the leaderboard) 3. Upgrading buildings usually show as destroyed, and are not selectable until complete (Really bad for high level Taverns, or PH for Plundercam) 4. Time remaining above upgrading buildings doesn't show when they are in destroyed mode. 5. Game crashes every few minutes, usually at the start of a battle. 6. He wasn't able to buy gems directly. Had to load island on another device to do it.
Everytime somebody says something like that I wonder if they are properly squatting on top of the toilet seat...
