Oh, Poke'mon is fun to roleplay, especially in Ficho. But I HATE it when a few attack others for no reason, thus giving us a sort of 'bad name'.
I imagine that they think that the lake is sort of their own place (I am not reffering to every. . well, Poke'mon; I personally enjoy sitting in party-chats with other people that don't feel like being constantly approached by strangers). It's somewhat like the way that some Warrior Cat clans will rudely try to kick you off their 'territory' rather than at LEAST asking nicely.
It's just another thing we have to deal with, really.
