"prevent useless farming" we'll do our best for preventing this. We're all passionated players before being game creators and we'll try to avoid putting in our game things we hate in other games.
We'll make game balance consistent, even with new worlds.

Right sorry I forgot to mention that > you'll soon be able to choose your class and not be imposed one class at random. This will be a major update in the overall gameplay and will hopefully add a lot of depth in Battles. I think we'll release this along with Leaderboards... because when you guys will be able to compete for rankings, you need to have all strategy options at your disposition I think

And well you're damn right, all what girls is to have orgasms, that's a golden rule :-D
