As someone who has been active on both, I don't think there's any real debate that sparring on Facebook is easier than sparring on an iDevice. It just is, and the amount of people that switched from poor iDevice sparrers to somewhat average Facebook sparrers is a good example of this. People suddenly having an easier ride for not using iDevices has created an iDevice elitism. It is understandable, given that this version originated as an iPhone game and still consists of a 90% iPhone playerbase -- there's only ever 100~ Facebook players online.

Thallen is correct though, but I don't think most people are understanding it. If you hold this belief that Facebook is easier, and own a PC which most people do, then the only thing that is stopping you from using it is yourself. Your own pride, I guess. It is a platform that is open to everyone and it is an intended part of the game. Things like the leaderboards are divided up so that skill is not being measured between the platforms. I don't understand what the problem is, nor why arguments on technicalities are being attempted. You're not forced to spar each other and you're only limited to what devices you own and your attitudes towards them.

The game is not intended for people on iDevices alone anymore. I don't like it much either, and I am known for sparring on Facebook, but that's just how it is.
