Conquest servers are a bad idea. Large scale PvP is basically what Official PvP is and you're taking players out of that pool yet again, contributing to the perception that the game is dead. Fragmenting your playerbase is generally a bad business decision, and the main deterrent to playing on Official is server lag so having permanent 2x servers with 100 slots isn't going to help that at all. You're better off shifting your attempts to solving the problems that cause players to not want to play Official such as improving server performance, disconnecting, etc if large scale battles is your goal. With these servers you're going to split the playerbase, making both clusters worse off overall.
