I hate to say it but this was one of my favorite commands in DotA. This makes sure you get heroes you're somewhat familiar with rather completely a complete random netting you a hero you're not even remotely familiar (I hate getting INTs when I want AGIs).
Isn't really a big deal for me - Random is Random.
