Ancient Size

I've observed that monster size doesn't appear fixed anymore. It seems that (From a LOT of hunting) that mobs start out at "normal" size. As time goes on, they get bigger, until they become "small" ancients. They keep growing until they despawn.

For example, this would explain why people have been seeing "regular sized ancients". They aren't regular, they're just very early on in the growth cycle. I've also seen a lot of mobs lately that look significantly larger than their companions, only to find out that they're still "normal" monsters.

Finally, look at this screenshot. Notice the size difference in the two Keepers the Ancients. I believe the bigger one was older. (Compare them to the regular keepers standing next to them)

Anyone thinks that as they 'grow' the drop rate increases too? This means that a bigger 'ancient' is more likely to drop something right?

Nah...I'm pretty sure it's fixed regardless of size..
