I really love the idea of a horde encounter. Being able to battle more Pokémon at the same time makes it much more fun and realistic to me. I am worried, though, that if it happens early in-game that my Pokémon will get knocked out easily by hordes (especially if I do not have a multi target move). On the other hand, it would be nice to be able to have them in the beginning. The EXP bonus would also be a great way to level up. Generally, I think wild Pokémon battles were too easy anyway, and this really spices things up!
