I see no problem whatsoever with character sizes. Mostly, when someone makes a character of a certain size they are only meaning to Rp with others of their species/size. A bunch of tiny wolves could be adult, but if they want to be small I say let them! Their group size is tiny, because they are only planning on RPing with their own group. I don't like people who gauge strength on size, because if it is a realistic RP, a lion sized warrior is still the size of a house cat, and a wolf is the size of a wolf, even if the wolf is 'pup sized'. Here's one of my personal experiences. I was just messing around in bonfire on my coyote, and decided I'd go eat the pups sit at adoption center. I was a full grown coyote, and someone tried to adopt me ._. Yet another example (I was still my coyote) is when I was watching a group of horses when two powerplaying coyotes came up and killed a foal. They didn't respond to any posts but their own, and just ate the foal no matter what we(me and the surrounding horses) would tell them about how coyotes can't kill a horse. V.V ~end rant~
