I actually agree. One should be able to make more than 10 characters. If you like to test out different things, which could be anything from character builds to NPC drops, then it's useful to have multiple characters. It's also useful for wiki related things, like getting screen shots of certain events/cut scenes, noting NPC dialogue, etc.

It's an arbitrary cap, and there really is no good reason for it.
